The correct answer is: A.it is polar.

Water is excellent at dissolving many substances because it is polar. This means that water molecules have a partial positive charge on the hydrogen atoms and a partial negative charge on the oxygen atom. These charges allow water molecules to interact with and break apart many types of molecules, especially ionic compounds (like salts) and polar molecules, effectively dissolving them.

Here’s how the other options relate:

B.Less dense as a solid: This is why ice floats on water, but it doesn't explain why water is such a good solvent.
