The surface lesion that is a blister is b. vesicle.

A vesicle is a small, fluid-filled blister that appears on the surface of the skin. It is typically less than 5 mm in diameter and may be caused by a variety of factors, including infections, allergic reactions, and friction. Vesicles can be painful or itchy, and they may rupture and form crusts as they heal.
