Answer:
I believe the option that is a conceit in the selection to be:
D) the poet's willingness to accept the same fate as a flower
Explanation:
A conceit is a type of figure of speech. It is similar to an extended metaphor, but it uses unconventional comparisons. In other words, it goes beyond by providing an intellectual and complex comparison between two things that are dissimilar. Conceit seems to be quite common in metaphysical poetry, since metaphysical poets tend to develop their subjects and topics in a more intellectualized or sophisticated manner.
<u>Having that in mind, we can see how comparing one's life to that of a flower is quite metaphorical. But Herbert goes beyond. Not only does he compare his life to that of a flower, but he even accepts the same fate. The flower does not live long, but it does serve a purpose both when it is alive and when it is dead (ornament and cures, respectively). The speaker wishes the same for himself - he wants his life to be as purposeful as the flowers, even if he does not live for a long time. That seems to be quite a metaphysical interpretation of the comparison and, therefore, a conceit.</u>
