After a heart attack, fibrosis occurs at the site of cardiac muscle cell death. This reduces the efficiency of the heart's pumping activity because Fiboros connective tissue is cannot contract.

Answer:

The correct answer is - Fibrous connective tissue is incapable of contracting.

Explanation:

Fibrous connective tissue is one of the tissue that provides the support and structure to the heart. These tissues are dense connective tissues that also help in isolating the ventricles and the atria.

After the heart attack, the heart muscles become stiffens due to fibrosis at the site of the cardiac muscle death which makes which leads to the unable to fill the atria at one go so reduce the pumping of the blood.

Thus, the correct answer is - Fibrous connective tissue is incapable of contracting.
