quadriceps femoris
rectus abdominus
iliopsoas
biceps femoris

Explanation:

In human anatomy, the quadriceps femoris is a large muscle group located on the anterior (front) of the thigh. The label J in the diagram points to this anterior thigh region, which matches the location of the quadriceps femoris. The rectus abdominus is in the abdomen, iliopsoas is in the hip area, and biceps femoris is on the posterior (back) of the thigh, so they are not the correct answer.

Answer:

quadriceps femoris
