Proteins are primarily associated with growth and repair in the body, while carbohydrates are mainly a source of energy. Thus, the analogy correctly pairs 'Proteins : Growth' with 'Carbohydrates : Energy.'

The analogy compares a scientist to their discovery or field of study. Roentgen is associated with X-rays, so similarly, Becquerel is associated with radioactivity, making option B correct.

Cells combine to form tissues, similarly atoms combine to form molecules. Therefore, the correct analogy is Atoms : Molecules.

The analogy compares similar meanings: 'Loiter' means to linger or 'dwandle' (a misspelling of 'dawdle'), both implying wasting time. 'Impugn' means to challenge or call into question, so the correct analogous word is 'Challenge'.

A cap is an item worn on the head, similarly, a thimble is an item worn on the finger. This analogy matches the relationship between the first pair.

Origami is the art of folding paper, so the related material is paper. Similarly, Ikebana is the Japanese art of flower arrangement, so the related material is flowers. Therefore, the correct analogy is Ikebana : Flowers.

The cockpit in an aeroplane is the area where the pilot controls the aircraft, essentially the control center. The equivalent part in a train is the engine or locomotive cab, where the driver controls the train. A compartment is a passenger section, not analogous to the cockpit. Therefore, the correct analogy is Aeroplane : Cockpit :: Train : Engine.

Dawn and dusk are opposite times of the day, representing beginning and end respectively. Similarly, inauguration marks the beginning of a term or event, and valediction signifies the farewell or end. Hence, valediction is the correct analogy to inauguration.

A 'Rondo' is a type of musical form, so it relates to 'Music' as a specific form relates to its general category. Similarly, a 'Lay' is a type of poem, so the correct analogy is 'Lay : Poem'.
