Answer:
OA. I went to look for my watch, but I can never seem to find the time.
Explanation:
A pun is usually a comical play on the actual statement itself. There usually two elements that are inter connected to each other in some way.
Let's look at A: watch and time correlate since a watch tells time. The statement is ironic the speaker doesn't have his watch, therefore figuratively but maybe actually as well "doesn't have the time". It's therefore a pun.
B: It's a different figurative language technique, but I'm not sure what it is. 100% sure it's not a pun though.
C: it's a metaphor. It's a comparison between two things, in this case the novel was so well explained it had he accuracy of hitting a nail directly on the head.
D: That's just a statement, maybe a poetic quote.
