Explanation:

Let’s break it down:

- Option 1: Rs 25,000 — this is the actual deposit required for a candidate seeking election as Vice-President of India. It’s set out in the Presidential and Vice-Presidential Elections Act, not the lower figure.

- Option 2: Rs 20,000 — this used to be the deposit amount for the Lok Sabha (lower house), not the Vice-President.

- Option 3: Rs 30,000 — this is too high and not the figure specified in law for this post.

- Option 4: Rs 15,000 — this is the deposit for contesting in a Lok Sabha parliamentary seat, not for the Vice-President’s office.

So, here’s the thing:

The correct answer is Option 1: Rs 25,000.
