C Correct answer
Explanation

Mitral regurgitation causes volume overload of the left ventricle and left atrium. This leads to pulmonary venous hypertension, which increases pulmonary blood volume. The increased residual volume occurs because of the elevated pulmonary venous pressure and subsequent fluid shifts. This is a manifestation of pulmonary congestion secondary to left-sided valvular insufficiency.
