Correct Answer: sliver fish

Solution : The correct option is Silver fish.

The "silver fish" is not a true fish. Silverfish are small, wingless insects that belong to the order Zygentoma, class Insecta within the phylum Arthropoda. They are often found in homes and feed on starchy materials like paper and book bindings. The other options, hammar fish (possibly referring to hammerhead shark), sawfish, and sucker fish, are indeed true fish and they represent specific types of fish within the broader classification of fish species.
