d. all of the above

As for this problem together with the options presented with it, the most likely answer and the most probable one would be the last option which is D. All of the above.

In active listening, it is important to pay attention. This is to take note of the information being shared and how you can provide feedback later on. It is also important in active listening to show that you really are listening. Simple gestures like nodding of the head and having an open posture in addition to looking at the person in the eyes are signs that you are listening. Providing feedback is also an integral part in active listening, and quite the tricky one. Some people doesn't want feedback and some wanted to hear it. So it rests on the judgement of the active listener as to provide feedback or not, and what feedback is to be given.
