The analogy 'Duralumin : Aircraft' relates a material to what it is commonly used to make. Duralumin is a lightweight, high-strength aluminum-copper-magnesium alloy widely used in aircraft construction as a structural material. The analogous pair should similarly relate a material to an object commonly made from it. Among the options, 'Bronze : Statue' correctly relates a material (bronze, an alloy) to a common product made from it (statue). Option A ('Brass : Alloy') merely states that brass is an alloy, which is a classification rather than a usage relationship. Option B ('Stone : Sculptor') relates a material to a person who works with it, not an object made from it. Option C ('Iron : Steel') relates a base material to another material (an alloy), not to a product made from it. Therefore, the best analogous pair is D ('Bronze : Statue').

The analogy 'Money : Transaction' shows that money is used to facilitate a transaction. Similarly, 'Ideas : Exchange' shows that ideas are exchanged. Thus, the relationship is about something being used or involved in a process. Option C best matches this relationship.

A barrel and a vial are both containers, but a vial is a smaller version of a barrel. Similarly, a pamphlet is a smaller version of a book, making option B the correct analogous pair.

The analogy 'Sailor : Pirate' relates a lawful or neutral seafarer to an unlawful or criminal one. Similarly, 'Police : Robbers' pairs lawful enforcers with criminals, making it the correct analogous pair. The other options do not reflect a similar relationship of lawful versus unlawful roles.

The analogy 'Cream : Cosmetics' shows that cream is a type or product within the category of cosmetics. Similarly, 'Teak : Wood' shows teak as a type of wood, making it the correct analogous pair. Option D ('Mountain : Valley') represents contrasting geographical features, not a category-member relationship.

A calendar contains dates, just as a dictionary contains words. Both pairs show a container-to-contained relationship, making option C the correct analogous pair.

The pair 'Inherit : Acquire' shows a relationship where 'inherit' refers to receiving something biologically or genetically (instincts are inherited traits), while 'acquire' refers to gaining something through experience or learning (habits are acquired behaviors). Thus, 'Instinct : Habit' is an analogous pair because instinct is an innate, inherited behavior, whereas habit is learned through experience. This relationship mirrors the original pair's contrast between innate and learned or acquired. Other options do not show this clear analogous relationship.

The pair 'Introduction : Conclusion' represents the beginning and the end of something. Similarly, 'Salutation : Farewell' represents the greeting at the beginning and the goodbye at the end, making them analogous pairs.

The analogy 'Rocket : Fuel' indicates that a rocket requires fuel to operate. Similarly, 'Man : Energy' means a man requires energy to function. This relationship is one of necessity or essential input for operation. Other options do not represent the same direct relationship: 'Machine : Oil' relates more to lubrication than essential energy, 'Current : Electricity' is a part-whole or type relationship, and 'River : Water' is a composition relationship rather than a functional necessity. Therefore, option A is the best analogous pair.

Graphite is used as a lubricant due to its layered structure, and similarly, diamond is used as an abrasive because of its hardness. This makes the pair 'Diamond : Abrasive' analogous to 'Graphite : Lubricant'.
