It seems like you're asking for the muscles located at the back of the trunk. The muscles in the back of the trunk primarily include:

1. Trapezius: This is a large muscle that extends down the back of the neck and upper spine. It helps in moving, rotating, and stabilizing the shoulder blade (scapula).

2. Latissimus Dorsi: These are large, flat muscles on either side of the back. They are the largest muscles in the upper body and are responsible for the movement of the shoulders and arms.

3. Rhomboids: These are located in the upper back, underneath the trapezius muscles. They are responsible for the retraction of the scapula.

4. Erector Spinae: This is a group of muscles and tendons running along the spine. They are responsible for the extension and bending of the spine.

The options you've provided include muscles from various parts of the body:

• Gluteus Maximus, Gastrocnemius, Hamstrings: Semimembranosus are muscles located in the lower body. The Gluteus Maximus is in the buttocks, the Gastrocnemius is in the calf, and the Semimembranosus is one of the Hamstring muscles in the back of the thigh.

• Deltoid, Trapezius, Extensor Carpi Radialis are muscles located in the upper body. The Deltoid is in the shoulder, the Trapezius is in the back, and the Extensor Carpi Radialis is in the forearm.

• Quadriceps: Vastus Lateralis, Tibialis Anterior, Fibularis Longus are muscles located in the lower body. The Vastus Lateralis is part of the Quadriceps in the thigh, the Tibialis Anterior is in the shin, and the Fibularis Longus is in the lower leg.

• Frontalis, Masseter, Buccinator are muscles located in the head. The Frontalis is in the forehead, the Masseter is in the jaw, and the Buccinator is in the cheek.

So, the option that includes muscles from the back of the trunk is "Deltoid, Trapezius, Extensor Carpi Radialis" with the Trapezius being the muscle in the back of the trunk.
