Hint: The center of gravity (CG) of an object is the point at which weight is evenly dispersed and all sides are in balance. A human's center of gravity can change as he takes on different positions, but in many other objects, it's a fixed location.

Complete answer:Mobility relates to movement while stability relates to control. Stability is defined as the ability to maintain control of joint movement or position by coordinating actions of surrounding tissues and the neuromuscular system. Joint stability depends largely on the shape, size, and arrangement of the articular surfaces (the surfaces on joints and cartilage where the bone makes contact with another bone), the surrounding ligaments, and the tone of the surrounding muscle. Injuries including ligament tears and sprains can often lead to stability issues in the joint.
So, the stability of objects depends on the base, C.G and shape of the body. For a body to be the stable,
The base of the body needs to be broad.
The Centre of gravity should be as low as possible.
The vertical line through the center of gravity should fall within the base.

So, all the options are correct.

NoteFlexibility is the absolute range of motion in a joint or system of joints, and the length of muscle that crosses the joint involved.1 It directly correlates with range of motion and mobility, but does not directly correlate with strength, balance, and coordination. Range of motion is the distance and direction the joint can move, while mobility is the ability to move without restriction.
