The correct answer is paracrine.

Explanation:

Paracrine signaling refers to a form of cell signaling in which a cell produces a signal to induce changes in nearby cells. This mechanism differs from endocrine signaling, where hormones are released into the bloodstream to affect distant target organs. Autocrine signaling occurs when a cell secretes a substance that binds to receptors on its own surface, influencing its own activity. Exocrine secretion involves the release of substances to external environments through ducts, such as saliva or sweat glands.

In paracrine signaling, the effects are localized to the nearby cells within a tissue, allowing for rapid communication and response within a specific area. This is essential in processes such as tissue repair, immune responses, and the coordination of cell behavior during development.
