According to the research, the correct option is C. Amphibians have a closed circulatory system this means fluids are contained in tubes.

<h3>What is the circulatory system?</h3>

It comprises the heart, arteries, veins and lymphatics and systems responsible for supplying oxygen and distributing blood to the different parts of the body.

In this sense, amphibians are tetrapod vertebrates that develop lungs whose blood circulates through a closed circuit of arteries and veins.

A closed circulatory system means that the blood, when circulating, always moves in the blood vessels, through which all the organs and regions of the body receive blood rich in oxygen.

Therefore, we can conclude that according to the research, the correct option is C. Amphibians have a closed circulatory system this means fluids are contained in tubes.
