After sunrise: The sun rises in the east.
Kavita's shadow is to the right of Reeta.
If they are facing each other and Kavita's shadow is to the right of Reeta, it means:
⇒ Reeta must be facing south (since her right would be towards the west, where shadows fall in the morning).
⇒ If Reeta is facing south, then Kavita, facing Reeta, must be facing north.
However, since Kavita's shadow is to the right of Reeta (and therefore to the west), Kavita must be facing south.
So, the correct option is (B): South.
