Explanation:

Let’s get into it.

- The Union Budget 2019-20 clearly estimated the total investment needed for railway infrastructure during 2018-2030.

- Here’s what the numbers looked like:

- Option 1: Rs 40 lakh crore — too low

- Option 2: Rs 50 lakh crore — this was the figure spotlighted in the actual budget speech, mentioned by the Finance Minister as the needed investment

- Option 3: Rs 60 lakh crore — that number’s overstated, not what was budgeted or discussed

- Option 4: Rs 30 lakh crore — again, much lower than the requirement laid out

The correct answer is:

Option 2: Rs 50 lakh crore

So, Rs 50 lakh crore is the figure you want to remember for that period. The government highlighted this as essential for upgrading, expanding, and modernizing India’s railways by 2030. That’s the core point.
