A

Fish Z because it lives near the ground.

B

Fish Y because it shows camouflage.

D

Text Solution

Verified by Experts

The correct Answer is:
D
Among the given fish, fish Z will be the most affected but not because it lives near the ground. It will be affected the most because it is most strikingly visible when tries to hide in the aquatic plants. Its body pattern does not match with that on weeds i.e., it does not show camouflage. So, predators can easily find and eat it.
