The answer is A) True because when someone is telling u something, u should always show that u are listening to them because it can be like this example here. Say for ex You and your wife are on your own private jet to fly to the Bahamas and your pilot passes out and there is no backup, in most cases u would usually call the emergency phone line and ask them how to fly this machine, when they call u back to give u the instructions, u HAVE to be listening, even if it is long or even boring to u, u HAVE to listen since your own very life is on the line, so that's why it applies back with use because if we are not carefully listening, even to anybody, if it is BIG or small, we should always show them we are aware and we are giving them our attention.
