The correct option is C Crescograph
Crescograph is a device for measuring growth in plants. It was invented in the early 20th century by Sir Jagadish Chandra Bose - an Indian polymath, physicist, biologist, botanist, archaeologist. The Bose crescograph, uses a series of clockwork gears and a smoked glass plate to record the movement of the tip of a plant at magnifications of up to 10000. Thus, the correct answer is option C.
