Answer 1

The correct option is B Geotropism

The positive response of the plants towards the gravitation is called geotropism. Geotropism means response to gravity if the response is in the direction of the gravity then it is called positive geotropism since root is growing downwards (in the direction of gravity) so it is called positive geotropism.

So the correct answer is "Geotropism".
