The appendicular skeleton includes the bones that make up the arms, legs, and the girdles (shoulder and hip) that attach them to the rest of the body. So, the correct option is "pectoral and pelvic girdles" and "forelimbs".
The pectoral girdle is made up of the scapula (shoulder blade) and the clavicle (collarbone). The pelvic girdle is made up of the two hip bones. The forelimbs consist of the humerus (upper arm bone), radius and ulna (lower arm bones), and the bones of the hand (carpals, metacarpals, and phalanges).
Together, the bones of the appendicular skeleton help us move around and carry out a wide range of physical activities, from running and jumping to manipulating objects with our hands.
