Solution

The correct option is A 1 ventricle and 1 auricle

Fish have 2 chambers, one atrium and one ventricle. Fish hearts draw in deoxygenated blood in a single atrium, and pump it out through a ventricle. This type of system is known as "single circulation type", as blood enters the heart, gets pumped through the gills and out to the body. Thus, the correct answer is option A.
