What happens once and item breaks through the surface of tension in water?

COLLISION

Surface tension is a phenomenon where liquid molecules resist an external force because if the cohesive forces between them. Neighboring molecules share the cohesive forces with the surface exhibiting stronger bonds (than below the surface). Floating needle and small insects walking on water are examples of surface tension. A collision bumps the molecules and crashes through the “film” of the surface, breaking the tension.

it sinks, I had this exact question on a test and this was the correct answer.

the correct answer is c
