The correct answer is (C) A message is distributed across plasma membrane.
Intercellular communication means the communication that takes place between two cells, gap junctions, target-receptor. This means the message is transferred between two cells and then carry forward by other cells like a cascade or signal transduction. When a message is transferred across plasma membrane this means that no other cell is involved in it. The message is transferred from one organelle to other within the cell. Inter cellular response is not restricted only upto a single cell.
