Indian Physical Geography

Directions east and west are wrong in most of the questions. Western part is the one on the Arabian sea side, not on the Bay of Bengal side.

Therefore, Lakshadweep is actually on the western side while Andaman & Nicobar islands are on the eastern side.

Similarly, coasts, waterbodies, and plateaus also need to be switched.

Also, be more explicit about which biggest lake you want - based on surface area, volume, or depth and such.
