The correct answer is c) different tissues differ in hormone receptors and intracellular effector proteins.

Here's why:

Hormones are chemical messengers that are secreted directly into the blood, which carries them to organs and tissues of the body to exert their functions. They are specific in their action, meaning they will only affect certain cells or tissues that have the necessary receptors to bind with the hormone. These receptors are like a lock, and the hormone is like a key. Only the correct key (hormone) can fit into the lock (receptor).

Different tissues have different types of receptors and respond to different hormones. This is why hormones act in a tissue-specific manner. For example, insulin is a hormone that affects only cells that have insulin receptors, such as liver, muscle, and fat cells.

Intracellular effector proteins are also important in this process. Once a hormone binds to its receptor, it triggers a cascade of reactions inside the cell, often involving these effector proteins. These proteins help to amplify the signal and produce the desired effect within the cell.

So, it's not that hormones are carried in the blood only to specific tissues (option b), or that endocrine glands affect only nearby tissues (option a), or that hormones are transported in axons only to specific tissues (option d). It's that different tissues have different receptors and effector proteins, allowing them to respond to specific hormones.
