Solution

The correct option is A True
Drosera also known as Sundew is one of the largest carnivorous plants. They capture and digest insects which they eat to supplement the poor mineral nutrition that they obtain from the soil in which they grow. They bear glandular tentacles which they use in capturing prey. The tentacles being extremely sensitive bend towards the centre of the leaf so as to bring the insect close to their glands. Since this bending takes place in response to the touch brought about by the insect, it is a type of thigmonasty
Thus, the correct answer is option A.
