Explanation:

Here’s the thing—let’s break this down option by option:

- Option 1: 2001

Valmiki Ambedkar Awas Yojana wasn’t launched in 2001.

- Option 2: 1999

This is the right year. The scheme started in 1999. Its main aim? To provide housing for urban slum dwellers, focusing especially on those from Scheduled Castes and Scheduled Tribes who don’t have their own homes.

- Option 3: 2005

This is too late—by then, the scheme had already been running for a while.

- Option 4: 2011

Definitely not the answer; the scheme was already established by then.

So the correct answer is option 2: 1999.
