The tropic movement in response to stimulus of touch is called thigmotropism. For example, climbing vines. When they come in contact with some solid object the growth on the opposite side of the contact increases. So tendril coils around the support.

(d) \bold{\huge{\red{Hydrotropism:}}}

The tropic movement of plant in response to stimulus of water is called hydrotropism. The growth of root toward water is due to positive hydrotropism. The shoot grow away from water is negative hydrotropic.

✳️✳️

(e)\bold{\huge{\red{Geotropism:}}}

The tropic movements in response to gravity are called geotropism. Root show positive geotropism, while shoot show negative geotropism.
