Solution

The correct options are
B Irreversible
C Physical
A change in which no new substance is formed and there is only a change in shape, size or state of a substance is called a physical change. A change in which we cannot obtain back the original substance after the change has occurred is called an irreversible change.
When Shreya drops the vase of glass, the glass breaks and scatters all over the floor. It is not possible to get back the same vase from the broken pieces. Hence it is an irreversible change. Also, only the shape of glass change and no new substance is formed. So, it is also a physical change.
