Solution
The correct option is B Chemotropism
The growth or movement of a plant or any part of the plant in response to a chemical stimulus is called as chemotropism. An example of chemotropism is the growth of a pollen tube down the style during fertilization in response to the presence of sugars in the style.
Phototropism is one of the many plant tropisms or movements which respond to external stimuli. It is called as positive phototropism when the plant growth is towards a light source.
Geotropism, which is also known as gravitropism, is characterized by the growth movement by a plant in response to the gravity. It is a general feature of all higher and many lower plants as well as other organisms.
Therefore, the correct answer is option B.
