Answer:
B. Persuasive
Step-by-step explanation:
1.) Upon reading 'To His Coy Mistress', one will notice that the main point of this passage is to persuade a woman to pursue him before it is too late (she becomes too old). It is also worth mentioning that Marvell believed essentially that women lost their beauty and value with age, which is why he is so adamant on finding a wife immediately, speaking of how time is of the essence.
2.) I just took an assignment with this question on it, chose the answer B, and got it correct.
Hope this helps! :)
