Option 2 : III and IV

The correct option is 2. i.e.

The movement of a plant part in response to light is called Phototropism. Hence, the statement I is incorrect.
- It can also occur in other organisms such as fungi.
The movement of plant part in response to gravity is called Geotropism. Hence, statement II is incorrect.
- The roots of the plants always grow downwards due to geotropism.
The movement of a plant part in response to a chemical stimulus is called Chemotropism.
- It can take place in bacteria, plants and fungi.
The movement of a plant part in response to water is called Hydrotropism.
