• A. Scales
• B. Stream lined body
• C. Fins
• D. Both B and C

Answer 1

The correct option is D Both B and C

The scales present in the outer body part of fishes act as a cover to protect them from predators, injuries, and parasites.

Fishes swim by flexing their streamlined bodies and tail back and forth. They stretch the muscles on one side and relax the muscles on the other side. This motion helps them to move forward (swim). The fishes use their caudal fin (back fin) to push themselves through the water.

Thus, a fish swims with the help of streamlined body and the fins.

So, the correct answer is 'Both B and C'
