Final Answer :
C
Explanation :
The small muscle masses attached to the chordae tendineae are called papillary muscles. Trabeculae carnea and pectinate muscles are both muscular structures found in the walls of the heart, but they are not associated with the chordae tendineae. The venae cavae are large veins that return blood to the heart, but they are not involved in the function of the chordae tendineae.
