Hi Debarpitchandra,
Learning SC is a slow process. Looks like you haven’t learned some of the basic SC rules. If you try to solve complete questions without learning the rules first, the results aren’t going to be as expected.
“Which” always modifies the immediately preceding noun. In your option A, the noun preceding which is light. The meaning conveyed is that light makes it easier to see clearly at night.
Hope this helps!
