Explanation:

A curved surface in a graduated cylinder is called a meniscus. Capillary action causes the water - air interface to curve. Option a describes how water moves against gravity due to attraction among water molecules (cohesion) and between water and the container (adhesion), which is related to capillary action.

Capillary action is the ability of a liquid to flow in narrow spaces without the assistance of, or even in opposition to, external forces like gravity. It occurs due to the combination of adhesive and cohesive forces. Option a correctly describes the movement of water against gravity which is a key aspect of capillary action.

Capillary action allows water to climb up the sides of a straw (or other narrow tubes) because of the adhesive forces between water and the straw material and the cohesive forces within water molecules.

Answer:

a. It explains how water moves against the force of gravity.
