Verified step by step guidance

Step 1: Understand the anatomy of the orbicularis oculi muscle. The orbicularis oculi is a circular muscle that surrounds the eye and is responsible for closing the eyelids and enabling facial expressions such as blinking and squinting.

Step 2: Review the body regions mentioned in the options. The regions include 'around the mouth,' 'in the lower leg,' 'in the chest,' and 'around the eye.'

Step 3: Match the function and location of the orbicularis oculi muscle to the correct body region. Since the orbicularis oculi is involved in eyelid movement and surrounds the eye, it is located 'around the eye.'

Step 4: Eliminate incorrect options. The orbicularis oculi is not located 'around the mouth,' 'in the lower leg,' or 'in the chest,' as these regions contain other muscles specific to their functions.

Step 5: Confirm the correct answer based on anatomical knowledge. The orbicularis oculi muscle is indeed located 'around the eye,' making this the correct answer.
