Solution
The correct option is C D
A growth response to gravity is known as geotropism. Roots are positively geotropic whereas shoots are negatively geotropic. Shoots grow in the opposite direction to the direction of gravity. This ensures that shoots grow upwards getting the leaves into sunlight.In the given diagram, shoot 'D' shows upward movements in opposite direction of gravity.Hence, the correct answer is option D.
