Explanation:
Hydrotropism (or hydrotrophism) is the growth or curvature of plant parts in response to water.
Example: Roots bending toward a moist area in the soil.
Other options:
B. Geotropism → response to gravity (roots grow downward, stems upward).
C. Phototropism → response to light (stems bend toward light).
Key point:
Water → Hydrotropism
Gravity → Geotropism
