The heart of a fish has ______ chambers.

Two

The correct answer is Option (4)- Two

The heart of a fish typically has Two chambers.

Explanation:

Fish have a two-chambered heart, consisting of one atrium and one ventricle. Blood flows from the body into the atrium, then is pumped into the ventricle, and finally, it is pumped out to the gills for oxygenation. This oxygenated blood is then distributed to the rest of the body. The two-chambered heart is a characteristic feature of fish and is less complex than the three-chambered or four-chambered hearts found in amphibians, reptiles, birds, and mammals.
