Solution
The correct option is A Thigmotropism Thigmotropism is a directional growth movement in response to a touch stimulus. It is found in twining plants and tendrils. Grape vine tendril entwines around a support due to thigmotropic movement. Nutation is the bending movement shown by plant during its development. Growth movement in response to gravity is called as gravitropism. Nastic movement in response to external stimulus is called as chemonasty.
