B) Fish is a vertebrate and has fins. Vertebrate is an irregular bone with a complex structure composed of bone and some hyaline cartilage, the proportions of which vary according to the segment of the backbone and the species of vertebrate.
Explanation:
- Fins are distinctive anatomical features composed of bony spines or rays protruding from the body of a fish.
- They are covered with skin and joined together either in a webbed fashion, as seen in most bony fish, or similar to a flipper, as seen in sharks.
- Apart from the tail or caudal fin, fish fins have no direct connection with the spine and are supported only by muscles.
- Their principle function is to help the fish to swim.
- Fins located in different places on the fish serve different purposes such as moving forward, turning, keeping an upright position or stopping.
- Most fish use fins when swimming, flying fish use pectoral fins for gliding, and frogfish use them for crawling.
