Explanation:

Surface tension is a property of liquids that arises due to the cohesive forces between liquid molecules. In water, these cohesive forces are relatively strong. When considering the options:

• Spreading out in a thin film is more related to wetting properties and adhesion (interaction with other substances) rather than surface tension.
• Surface tension actually makes water molecules more "sticky" (cohesive) to each other at the surface, not less.
• Surface tension causes water to form droplets (clump together) because the molecules at the surface are pulled inward by the cohesive forces, minimizing the surface area.
• Surface tension allows light objects (like insects) to "float" or stay on the surface, not sink.

Answer:

It makes water tend to clump together in drops.
