Refer to the plot of temperature versus time (figure) showing the changes in the state, if ice on heating (not to scale). Which of the following statement is correct?
(a) The region \( A B \) represents ice and water in thermal equilibrium.
(b) At \( B \) water starts boiling.
(c) At \( C \) all the water gets converted into steam.
(d) \( C \) to \( D \) represents water and steam in equilibrium below boiling point.
