The correct answer is D. My mistress is not a perfect beauty.
Explanation:
In this poem, Shakespeare describes his mistress by referring to physical features such as her eyes, lips, breast, hair, etc. Additionally, through this physical description, Shakespeare emphasizes the woman is not perfect, this can be seen in "My mistress' eyes are nothing like the sun" or "If hairs be wires, black wires grow on her head" because these details show the eyes and hair of the woman are not especially beautiful or perfect.
However, this does not affect the love of the author for this woman, which is explained in " And yet by heaven, I think my love as rare, As any she belied with false compare." According to this, the main point or central idea is that the woman is not a perfect beauty and despite this the author feels a profound love for her (option D.)
