The Scapula is part of the pectoral girdle, which attaches the upper limbs to the body. The scapula is a flat, triangular bone that supports the muscles of the shoulder joint. 

The Ischium, on the other hand is part of the pelvis, which helps support the upper body's weight and balance. The ischium is also part of the acetabulum, a ball and socket joint formed by the pelvic bone and femur. The scapula is part of the appendicular skeleton, while the ischium is part of the pelvic girdle.

In summary, the appendicular skeleton also includes the upper and lower limbs, the bones of the hands and feet, and the pelvic girdle.- Option C
