The Attempt at a Solution

When we will move the contact X towards P, the potential difference should be maximum across the potential divider. I work out A as my answer but I think it is wrong.

Yes, that is incorrect.

True, but how does this affect the bulbs? What is the potential difference across lamp 1 when you connect X to P?

Let's say the battery is 12v.
What is the voltage at node P?
What is the voltage on the slider X when it's at P?
What is the voltage on each side of lamp 1?
What is the difference between each side of lamp 1?
