Let's read the text again...
My grandfather the fisherman always told me that the best way to communicate with fish is to drop them a line.
There are three phrases that help us to understand the pun in the text: The grandfather is a fisherman, it means his job is to catch fish, by communicate he means to make the fish come closer, and by drop them a line he means the fishing rod thread.
Taking the above into account the correct answers are:
A.“communicate” and “drop them a line”
B.The pun plays on a phrase that means both to send a note and to attempt to catch a fish.
The correct answer is B indeed. It is an example of plain folks because the speaker appeals to the citizens of his town, and to the knowledge that he shares with the other members of the community. This strategy is quite basic, as shown by this example, because the author makes a claim that most people would agree with, without actually providing evidence or a series of logical arguments.
