Answer 1

Explanation:

Statement 1: Shamita is taller than Rekha. Rekha is shorter than Tanya.

This implies Rekha < Tanya /Shamita.
- The shortest person is Rekha as per Statement 1.

Statement 2:

Rekha is shorter than Surbhi.
- Rekha < Surbhi
Surbhi is taller than Shamita.
- Surbhi < Shamita
Tanya is shorter than Surbhi.
- Tanya < Surbhi
Combining all these,
- Rekha / Tanya < Surbhi < Shamita
- The shortest person can't be determined as per Statement 2.

Hence, A is the correct answer.
