The combining form for the femur (thigh bone) is?

Explanation:
Terms for bones use a bone root plus a combining vowel. For the thigh bone, the root is femor-, and its combining form is femor/o. This lets you attach suffixes to make proper terms, such as femoral, which means relating to the femur. You can also see it in compounds like femoralgia (pain in the femur). The other options correspond to different bones: humer/o (upper arm bone), tibi/o (tibia), and fibul/o (fibula). So the combining form that names the thigh bone is femor/o.
