Explanation:

- In December 2020, Bank of Baroda launched the Atmanirbhar Women Scheme as a part of its Baroda Gold Loan initiative.

- The scheme is specifically designed to offer financial support to women, encouraging them to become 'Atmanirbhar' or self-reliant.

- Under this scheme, loans are offered to women at a concessional rate.

- The available options for the loan concession rate are:

- Option 1: 0.25%

- Option 2: 0.75%

- Option 3: 0.85%

- Option 4: 0.50%

- Option 5: 1.00%

The correct answer is Option 4, which is a 0.50% concession.
