Correct option is C
Raising the head to straighten the neck is called a chin tuck. It's a posture exercise that can help improve neck strength, flexibility, and function.
How to do a chin tuck:
1. Keep your head straight and your chin parallel to the floor.
1. Pull your chin back toward your chest, as if you're making a double chin.
1. While your chin is tucked in, move the back of your head away from the base of your neck.
1. Hold the position for three deep breaths.
1. Return to a normal chin position, and repeat.
Chin tucks can help counteract chronic forward neck posture and improve slouched posture.
