Which statement best describes paracrine signaling?

Explanation:
Paracrine signaling involves cells releasing signaling molecules that affect neighboring cells in the same tissue. The molecules diffuse through the surrounding fluid and act locally, rather than traveling through the bloodstream to distant targets. It also doesn’t require direct cell-to-cell contact. This is distinct from autocrine signaling (where signals act on the secreting cell itself) and endocrine signaling (where signals travel long distances via blood). An example is local growth factors that stimulate nearby cells during tissue repair. So, signals act on nearby cells is the best description.
