Explanation:

Alright, let’s break it down:

- The RBI has clear rules for non-banking entities wanting to act as a Bharat Bill Payment Operating Unit (BBPOU) under BBPS.

- The actual requirement is a minimum net worth of ?100 crore—not 100 lakh crore, just ?100 crore.

- None of the options (Rs. 500 lakh crores, 400 lakh crores, 300 lakh crores, 200 lakh crores, 100 lakh crores) are correct.

- “Lakh crores” is an enormous amount (1 lakh crore is 1 trillion!), way beyond what regulators actually demand.

- For context: ?100 crore = ?1,000,000,000, which is the actual RBI stipulation.

Here’s the answer:

- None of the options are correct. The correct figure is Rs. 100 crore (not Rs. 100 lakh crores).
