Final answer:
The muscle responsible for scapular depression and adduction, especially focusing on the lower trapezius, is the Lower trapezius. The option (D) is correct.
Step-by-step explanation:
The muscle primarily responsible for scapular depression and adduction, with a particular emphasis on the lower trapezius, is the Lower trapezius. The lower part of the trapezius muscle is key in contributing to these movements. Scapular depression is the downward movement of the scapula, which moves the shoulder blades down the back, while adduction refers to the movement of the scapula towards the spine.
The lower trapezius works in conjunction with other muscles to perform these actions effectively, providing stability and movement to the scapular region. Therefore, option (D) is correct.
