False

Either A or B

|
None of the above

Explanation:
Detailed explanation-1: –Thus function of chordae tendineae is to anchor the AV valves to ventricular papillary muscles and keep the AV valves in a closed position during ventricular systole to prevent the backflow of blood into the atria.
Detailed explanation-2: -The atrioventricular heart valves (AHVs) are responsible for directing unidirectional blood flow through the heart by properly opening and closing the valve leaflets, which are supported in their function by the chordae tendineae and the papillary muscles.
Detailed explanation-3: -Both the papillary muscles and the tendinous cords help to keep the AV valves securely closed during ventricular contraction.
