Question

test major bones
○ patella
○ calcaneus
○ tarsals
○ clavicle

Explanation:

The image shows the knee area with a highlighted bone. The patella is the kneecap, which matches the highlighted bone at the knee. Calcaneus is the heel bone, tarsals are ankle bones, and clavicle is a collarbone (not in the knee region). So the correct option is patella.

Answer:

A. patella (assuming the first option is labeled as A, but since the options are presented with the first being patella, the correct answer is the option with "patella")
