Right answer is (a) True

To elaborate: The function of the source and sink is interchangeable. During the favorable season, leaves acts as a major source transferring food to sugar storage organs which act as a sink. During dry season, these storage organs act as a source and the sink leaves as well as other organs become the sink.
