The correct answers are A and B
The answer is; B.
Cells have different receptors on their surfaces that are responsive to particular signals (such as hormones). When a signal interacts with the particular receptor, a particular response is invoked in the cell. This signal may be produced even by a cell that may be far away from the target cells. This is how cells communicate with each other to maintain homeostasis in the body.
