Answer:
(b).,Releases some heat is the correct option!!
When the liquid water turns to solid ice we find that water freezes without getting any colder. That's because the latent heat of fusion is being lost from the liquid as it solidifies and the temperature of the water does not fall so quickly.
Hence, the correct option is B
