Option A is grammatically correct and uses appropriate vocabulary. Option B is incorrect because 'utilizations' is not commonly used in this context and the verb agreement is wrong ('makes' should be 'make' if plural). Option C is a duplicate of A but the question asks to select the correct sentence, so the first correct option A is preferred. Option D is incorrect as there are correct sentences provided.

The lens in the human eye is a biconvex lens, which converges light rays to focus images on the retina. Biconcave lenses diverge light and are not found in the human body for vision purposes.

The nth term of an arithmetic progression (A.P.) is given by Tn = a + (n-1)d. Here, a = 3, d = 6, and n = 9, so T9 = 3 + (9-1)*6 = 3 + 48 = 51.

Rearranging the equation 4/x √(10x - 4) - 8 = 0 and solving for x yields x = 2 as the valid solution. Substituting x = 2 satisfies the equation, while x = 4 does not.

The Hakla-D.I Khan Motorway is officially designated as M14. Therefore, option B is correct, and option C is incorrect.

The European Union has announced plans to ban the sale of new conventional combustion engine cars by 2035 as part of its strategy to reduce carbon emissions and promote electric vehicles. This makes option A the correct answer.

The sentence "The lady in the blue dress has won the prize." contains a single independent clause with a subject and a predicate, making it a simple sentence. It does not have multiple independent clauses (compound) or dependent clauses (complex).

The term 'proletariat' refers to the working class or lower class in society, especially in Marxist theory. Therefore, option A, 'Lower class,' is the correct meaning.

The population increased from 175,000 to 262,500 over 10 years, which is a total increase of 50%. The average annual percent increase is calculated as (50% ÷ 10) = 5%. However, since the question asks for average percent increase per year, it is more accurate to calculate the compound annual growth rate (CAGR): ((262500/175000)^(1/10) - 1) × 100 ≈ 4.75%. Therefore, option A is correct.
