The correct answer is B, a vine wrapping around a fence.
Explicación
## Step 1Thigmotropism is a type of plant growth that occurs in response to touch or physical contact with a solid object. This is a common characteristic of climbing plants, which use thigmotropism to help them grow and climb.## Step 2Looking at the options provided, we need to identify which one best represents thigmotropism. ## Step 3Option A, a sunflower turning toward the sun, is an example of phototropism, not thigmotropism. Phototropism is a plant's response to light, where the plant grows towards the light source.## Step 4Option B, a vine wrapping around a fence, is an example of thigmotropism. The vine is responding to the physical contact with the fence by wrapping around it.## Step 5Option C, roots growing toward water, is an example of hydrotropism, not thigmotropism. Hydrotropism is a plant's response to water, where the plant grows towards the water source.## Step 6Option D, a seed sprouting in the soil, is a general process of plant growth and does not specifically represent thigmotropism.
