Explanation:

Let’s break it down:

- On 15th March 2021, the Supreme Court of India had only 1 woman judge—Justice Indira Banerjee.

- Option 1 (5 women judges): Too high. The court has never had 5 women judges at the same time.

- Option 2 (2 women judges): Also not right. There was just one.

- Option 3 (4 women judges): Not correct. Four women judges have never sat together in the Supreme Court.

- Option 4 (3 women judges): Still off. The number was just one.

So, the correct option is Option: 2, 1.

Option: 2 is correct.
