Answer:
They move faster.
Step-by-step explanation:
Given that water evaporates in a glass of water.
We have to find the reaction of the molecules of water.
Whenever evaporation happens to liquid substance water, the liquid is converted into gas. So when water evaporates, the molecules start to move quickly so that they escape into the atmosphere as molecules of water vapour.
Hence answer b) they move faster is right.
