Solution

The correct option is A Elongation
An auxanometer is an apparatus for measuring the increase or rate of growth in plants. In case of an arc auxanometer, there is a wire fixed with the plant apex on one end and a dead - weight on the other. It passes over a pulley which has a pointer attached to it. When the plant's height increases, the pulley rotates and the pointer moves on a circular scale to directly give the magnitude of growth.
