B. Lipoma
C. Myxoma
D. Papilloma

Answer 1

The correct answer is C. Myxoma. A myxoma is a primary benign cardiac tumor that is found most often on the endocardial surface of the atrioventricular valves or valvular endocardium. Myxomas are the most common type of primary cardiac tumor and usually occur in the left atrium, causing symptoms such as shortness of breath and fatigue.

Step-by-step explanation:

The correct answer is C. Myxoma. A primary benign cardiac tumor that is found most often on the endocardial surface of the atrioventricular valves or valvular endocardium is called a myxoma. Myxomas are the most common type of primary cardiac tumor, and they usually occur in the left atrium. They are often pedunculated, which means they are attached to the endocardium by a stalk or a pedicle. Myxomas can cause symptoms such as shortness of breath, fatigue, and palpitations.
