Explanation:

Hey mate !

Question:-

Which body parts helps the fish to swim ?

• Tail

• Fins

• Scales

• Forelimbs

Answer:-

The correct option is tail.

Reason:-

According to the question,the body parts which helps the fish to swim is tail because in every body which floats on water has to push the water back in order to move forward. This pushing back of water for fish is done by it's tail as the tail moves in a zig-zag movement to push the water back and helps the fish in moving forward.

★ Why 2nd option is not correct ?

Ans- The second option is fins and the find also help the fish in swimming but it varies with every species of fish. Fishes like dolphin,whales,sharks,etc don't have fins as they have forelimbs. So,this option doesn't apply to the whole variety of fishes but only for a some fishes. So,thus option is not totally correct.

★ Why 3rd option is not correct ?

Ans- The third option is scales and it has the function to protect the fish's body from the water by a wax-like layer otherwise the fish will rot in water. However,this option doesn't relate anywhere to swimming and so,it is not correct.

★ Why 4th option is not correct ?

Ans- The fourth option is forelimbs and as explained in 2nd option's explanation,the option 2nd and 4th only refers to a particular type of fish,so this option is also not correct.
