Verified step by step guidance

Step 1: Understand the anatomical term 'brachial region.' The brachial region refers to the upper arm area, specifically the region between the shoulder and the elbow.

Step 2: Review the location and function of each muscle listed in the options: - Deltoid: This muscle is located in the shoulder region and is responsible for arm abduction. - Flexor carpi radialis: This muscle is located in the forearm and is involved in wrist flexion. - Biceps brachii: This muscle is located in the brachial region (upper arm) and is responsible for flexing the elbow and supinating the forearm. - Pectoralis major: This muscle is located in the chest and is involved in arm adduction and rotation.

Step 3: Identify which muscle is specifically located in the brachial region. Based on the anatomical descriptions, the biceps brachii is the muscle located in the upper arm (brachial region).

Step 4: Confirm the correct answer by cross-referencing the function and location of the biceps brachii with the definition of the brachial region. The biceps brachii fits both criteria.

Step 5: Conclude that the correct answer is 'Biceps brachii,' as it is the only muscle listed that is anatomically located in the brachial region of the arm.
