The collarbone is known as:

B) clavicle

Explanation:
Clavicle: This is the correct answer. The clavicle, commonly referred to as the collarbone, is a long bone that serves as a strut between the shoulder blade and the sternum (breastbone). It plays a crucial role in the structure of the shoulder and allows for the mobility of the arm.

Scapula: This is known as the shoulder blade, which is located at the back of the shoulder and connects with the clavicle and humerus.

Pelvic girdle: This refers to the bony structure that connects the spine to the femurs (thigh bones). It is not related to the collarbone.

Chevron bone: This term is not commonly used in anatomy to refer to the collarbone or any other major bone in the human body.

In conclusion, the collarbone is specifically called the clavicle.
