tough, Fibrous strings

Part of the inside walls of the ventricles
C
Muscle
D
None
Explanation: 

Detailed explanation-1: -The chordae tendineae are small fibrous strings that originate either from the apical portion of the papillary muscles or directly from the ventricular wall and insert into the valve leaflets or the muscle. These 2 types are called true chordae tendineae and false chordae tendineae, respectively.

Detailed explanation-2: -Chordae tendineae maintain the position and tension of the atrioventricular valves (tricuspid and bicuspid valves). They maintain the one-way blood flow from the auricle to the ventricles.

Detailed explanation-3: -This link is usually arranged in a branching network of avascular tendinous chordae composed of collagen and elastic fibres, which transmit contractions of the papillary muscle to the valve leaflets.
