1. It was weaker than usual and shifted west.
2. It was robust (stronger) with its core shifted to the east.
3. It completely dissipated during July.
4. It remained exactly on its climatological position.
Option: B
The end of the SWM is officially declared by IMD when certain atmospheric conditions (like anti-cyclonic circulation) are met over Northwest India.
