Complete answer:
-The operculum is the cover that protects the fish's mouth, nose, and gills.
-The fish's nose is A, and the fish's eye is B.
-Fins consist of stiff rays or scales that are coated in skin. It aids the fish in swimming. Fins such as dorsal, caudal, and lateral fins are seen on the fish. The dorsal fin is the side fin of a fish that offers stability while swimming. The caudal fin, also known as the tail fin, is the main propulsive fin and is located near the back of the animal. This fin aids in shifting swimming directions.
-The dorsal fin is C, and the caudal fin is D.
-Fins are often used as foils to provide lift or push, or to steer or stabilise motion while travelling in water, air, or other fluids. Fins can also be utilised to improve surface areas for heat transmission or as decorative elements. Fins evolved as a mechanism of propulsion for fish.
-Another form of fin that helps with swimming stability is the anal fin. The anal fin is denoted by the letter E.
-The anal fin is present on the ventral side of fish, usually at the base of the anus, but not always. The anal fin, like the dorsal fin, serves to support the fish and prevent it from rolling around in the water.
-The pectoral fins aid in propulsion and movement from side to side. The letter G stands for pectoral fin.
As a result, option C is the proper response.
Note: Rohita labeo Rohu, also known as Carpo fish, contains a significant amount of protein. Omega 3 fatty acids, as well as vitamins A, B, and C, are abundant. At least once a week, you should eat Rohu.
