The correct answer is D. Seedlings planted in containers that are tipped over sideways extend their roots downward.
Gravitropism is the growth or movement of an organism in response to gravity. In this observation, the seedlings are responding to the change in orientation caused by tipping the container sideways by growing their roots downward, which is a characteristic response of gravitropism.
