The density of water is maximum at
4∘C. Let 'x' amount of ice has
been melted. Then the volume of
water at 20∘C displaced
to float that 'x' amount of ice
will be higher than the volume
of water that has been gained
after melting of ice as both volumes
have same masses 'x' but the density
is higher at 4∘C. consequently, the
water level falls
Option −B is correct
