Solution
The observation that would best support the scientist's claim that the umbrella-like structure of dandelion seeds increases the plant's reproductive success is (Choice B) Dispersed seeds are more likely than non-dispersed seeds to grow into new plants and survive. This is because the ability of the seeds to disperse and grow into new plants directly contributes to the reproductive success of the dandelion plant.
