Why is a coin able to float on top of water in a glass

1. Surface tension is the result of water molecules pulling inward with a strong attractive force.  

2. The attractive force brings the molecules on the surface of the water close together.

3. The attractive force causes the surface of the water to be drawn toward the water molecules beneath the surface.  

4. Since there are no water molecules above the surface, there are uneven forces. This causes surface tension, allowing the coin to float on the water’s surface.

THE ANSWER IS B

if i am not mistaken it is B because if it was  low it wouldve been  a solid and then medium would make it turn into a liquid and high would turn into a gas :)

i am correct plz give :)
