Which of the following is not a fish?a)Sharkb)Eelc)Electric rayd)Jelly...
Explanation:

Not a fish:
- Jellyfish are not classified as fish because they do not have a backbone or skeleton made of bone like true fish do.
- Instead, jellyfish are classified as invertebrates and belong to the phylum Cnidaria.
- They are made up of a gelatinous substance and have a simple body structure without organs like a heart or brain.

Fish:
- Sharks, eels, and electric rays are all examples of true fish.
- Fish are vertebrates that have a backbone or spine made of bone.
- They also have gills for breathing underwater and fins for swimming.

Conclusion:
- In summary, while sharks, eels, and electric rays are all types of fish, jellyfish are not considered fish because they lack certain characteristics that define true fish.
