Answer;

A. Blood

Explanation;

The main organs of the Circulatory system are the heart, the brain, the lungs. There are other key things like arteries, veins, and capillaries but they are not organs.

The major tissues in the circulatory system are the epithelial, muscle, nervous, and connective tissues.
