The correct answer is option b.Explanation:Aldosterone is a mineralocorticoid, that is, a steroidal hormone that plays important role in regulating blood pressure as well as the levels of sodium and potassium in the plasma.It is released from adrenal gland. Being steroidal in nature, it is capable of bypassing plasma membrane easily. However, its receptors are present inside the cell, that is, in cytoplasm.These receptors are expressed or present only in the target cells due to which this hormone produces its effects only in the target cells.Once bound to intracellular receptor, the cell signalling results in alterations in gene expression which produces the desired effects.

.3.The hormone is released into the bloodstream where it can be transported to all cells with the correct receptors.Explanation: The mode of transportation of hormones is bloodstream.They used the  medium  to reach the target cells.This makes the  hormonal effects relatively slower compare to eletrical transmission in the Nervous system.

DExplanation:Similarity of the drug molecule to other molecules transported by the target cells.

option B) intracellular receptors are present only in target cells.Explanation:The cell membrane or plasma membrane is composed of phospholipids and thus hydrophobic in nature, this allows the lipid soluble signaling molecules to cross the membrane. The cell membrane of all cells consist of phospholipids thus hydrophobicity of each cell membrane allows lipid soluble signaling molecules to pass through the plasma membrane. The testosterone cross the membranes of all cells but affect only target cells because of intracellular recepters that are located in target cell. The binding of signaling molecules to recepter generates a response. Thus, option B is correct.
