Answer:

A.Hydrotropism is a form of tropism characterized by the growth or movement response of a cell or an organism to moisture or water. The response may be positive or negative. An example of positive hydrotropism is the growth of plant roots towards higher relative humidity level.

B.Positive phototropism is growth toward a light source, and negative phototropism is growth away from a light source. Plant roots tend to exhibit negative phototropism, because they need to grow deeper into the ground for plant stability, water, and nutrients.PLEASE MARK THIS THE BRAINLIEST
