Solution

The correct options are
A Melting of chocolate
B Boiling of water
State change occurs when matter changes from one state to another. During melting of chocolate the state of chocolate changes from solid to liquid. During boiling, the state of water changes from liquid to vapour. Hence, change in state is observed in these cases.
Pouring of milk in tea and cutting of vegetables does not involve any state change.
