Step 1: Understand what the award recognizes.
The BBC Indian Sportswoman of the Year Award honors an Indian woman athlete's performance over the year, decided through public voting.
Step 2: Eliminate names from other fields.
Divya Deshmukh and Preethi Pal are strong athletes too, and Anjali Bhagwat is a retired shooter, but the 2025 winner was announced from cricket.
Step 3: Confirm the actual winner.
Smriti Mandhana, recognized for her consistent international cricket performances, was named the winner for 2025.
