Explanation:

- At sunset, the sun is in the west, so shadows fall towards the east.

- Lopa and Kritika are facing each other.

- If Kritika is facing a certain direction, Lopa is facing the opposite direction.

- The shadow of Lopa falls to Kritika’s right.

- For a person’s shadow to fall to their right in the evening, the person must be facing South (since west is to their right, and shadow falls eastward).

- Hence, Kritika must be facing South.

Correct Option:

Option:1, South
