Answer :
The correct answer is A. The figurative language in two poems.
Explanation:
The objective in a compare and contrast essay is to explain the differences/ similarities between two or more elements of the same category. Due to this, when selecting possible subjects it is important to analyze if they belong to the same category, for example, you can compare the achievements of two basketball players but it would be difficult to compare the achievements of a baseball player versus the achievements of a professional swimmer.
According to this, "the figurative language in two poems" shows a good point of comparison for a compare and contrast essay because it includes two subjects or texts of the same kind (poems) and the point analyzed in both is the same, which means the two subjects belong to the same category and therefore it is possible to explain their differences and similarities.
