Verified step by step guidance

Step 1: Begin by identifying the function and location of the adductor longus muscle. The adductor longus is part of the adductor group of muscles located in the medial compartment of the thigh. Its primary function is to adduct the thigh at the hip joint.

Step 2: Understand the attachment points of the adductor longus muscle. The muscle originates from the pubis (specifically the superior ramus of the pubis) and inserts onto the middle third of the linea aspera of the femur.

Step 3: Review the anatomical location of the femur. The femur is the thigh bone and is the largest bone in the human body. It serves as the attachment site for many muscles, including the adductor longus.

Step 4: Eliminate the incorrect options based on anatomical knowledge. The fibula and tibia are bones of the lower leg, and the humerus is the upper arm bone. None of these are associated with the adductor longus muscle.

Step 5: Conclude that the correct answer is the femur, as it is the bone where the adductor longus muscle inserts.
