Final answer:
The correct answer to the question is d, seeds are dispersed by wind, animals, and people, which helps spread seeds to new locations for potential growth.
Step-by-step explanation:
Based on the evidence provided in the text, seeds are dispersed by wind, animals, and people. This is a process by which seeds are spread from the parent plant to new locations, aiding in their potential growth into new plants given the right conditions. Various plant adaptations support this process, such as the dandelion seeds having parachute-like structures to be carried by wind, coconuts traveling via water, and acorns being buried and forgotten by animals. Seed dispersal is crucial for the propagation of species, as it allows seeds to find favorable environments with less competition where they can germinate and grow.
