Stability of the body is inversely proportional to ................... .
Answer: B
Stability is inversely proportional to the height of the body, that is, the height of its centre of gravity.
The higher the centre of gravity above the base of support, the smaller the tilt needed to carry the line of gravity outside the base, so the less stable the body. That is why athletes crouch and lower their centre of gravity to resist being pushed over.
The other factors work the other way: stability increases with body weight, with the size of the base of support, and with the distance of the line of gravity from the edge of the base. All three are directly, not inversely, related to stability.
