The correct option is (a) The product of centroid and weight to the total weight

For explanation I would say: The product of the centroid of the section to its weight to the total weight of the body is the centre of gravity. Thus the answer. The ratio is generally used to locate the coordinate of the centroid or the centre of gravity.
