Answer #1

Option B - Mitral regurgitation

Mitral regurgitation is due to the improper and incomplete closing of mitral valve that present between the left atria and left ventricle. Due to incomplete closing the blood from left ventricle enters left atrium when the ventricle contracts

Aortic stenosis - reduced diameter of aortic valve cause poor blood flow from the left ventricle into aorta

Mitral stenosis - reduced diameter of mitral valve cause poor blood flow from the left atrium to the left ventricle
