Answer: C -Half kneeling is a derived position.

Half kneeling is a derived position from kneeling in which one knee supports most of the body weight and the other knee is bent to create a right angle from hip and ankle. The foot is supported on the ground in a forward direction. Derived positions are derived from the starting positions to modify the gravity acting on the positioning of the body in order to perform exercises.

Hanging, sitting and standing are starting positions. Starting positions are postures from which movement is initiated.
