Verified step by step guidance

Step 1: Understand the anatomy of the deltoid muscle. The deltoid muscle is a large, triangular muscle that covers the shoulder joint and is responsible for arm abduction, flexion, extension, and rotation.

Step 2: Review the attachment points of the deltoid muscle. Muscles attach to bones at specific points called origins and insertions. The deltoid muscle originates from the clavicle and scapula and inserts onto the humerus.

Step 3: Identify the insertion point of the deltoid muscle. The insertion is the point where the muscle attaches to the bone it moves. For the deltoid muscle, this is the deltoid tuberosity of the humerus, a raised area on the lateral side of the humerus.

Step 4: Compare the options provided in the question. The olecranon process of the ulna, acromion process of the scapula, and coracoid process of the scapula are not the insertion points of the deltoid muscle. The correct answer is the deltoid tuberosity of the humerus.

Step 5: Conclude that the deltoid tuberosity of the humerus is the bony process to which the deltoid muscle attaches, based on anatomical knowledge and the function of the muscle.
