Match the List-I and List-II and select the correct answer from the codes given below :

Answer: C

The correct matching is a-4, b-3, c-1, d-2.

A scroll lake (oxbow or scroll-bar lake) forms on the inside of a river meander.
An alluvial fan builds up where a stream leaves the mountains at the piedmont and drops its load.
At a river mouth a delta splits the river into distributaries.
In a desert neighbouring alluvial fans merge into a bajada along the mountain foot.

Option A puts the scroll lake with distributaries and option B puts it with a bajada; option D links it with the piedmont, so only C fits all four.
