Final answer:
The correct answer is C) The digastric notch is the location where the posterior belly of the digastric muscle attaches, playing a key role in the movements associated with swallowing and jaw control.
Step-by-step explanation:
The digastric notch is a specific location on the human skeleton where a particular muscle attaches. It is not located on the thigh bone, nor is it where the triceps muscle attaches. The posterior belly of the digastric muscle, which elevates the hyoid bone and larynx when swallowing and also depresses the mandible, attaches at this location. Therefore, the correct answer is C) The digastric notch is where the digastric muscle attaches.
