Correct answer: The statement “the S₁ or lubb sound of the heart is produced by the closing of the AV valves” is true.

Explanation of Solution

The heart produces the “lubb” and “dubb” sound due to the closure of the heart valves. The heart has four valves, two semilunar valves, and two atrioventricular (AV) valves. The mitral valve or bicuspid valve and tricuspid valve are atrioventricular valves situated between atria and the ventricles. The closure of AV valves creates the first sound the S₁-“lubb”.
