A field biologist measured how far four woodland wildflowers scatter their seeds, hoping to learn what governs the distance. For each species she recorded the average mass of a single seed and the average distance a seed traveled from the parent plant. Her results appear in the table.

Species	Mean seed mass (mg)	Mean dispersal distance (m)
Bellflower	0.3	12
Wood aster	0.9	12
Cranesbill	2.1	6
Hazelwort	4.5	2

The biologist hypothesized that, in these wildflowers, seeds with a smaller mass are carried farther from the parent plant. Which choice most effectively uses data from the table to support this hypothesis?

ABellflower seeds, the lightest at 0.3 mg, traveled an average of 12 m.

BHazelwort seeds, the heaviest at 4.5 mg, traveled an average of 6 m.

CBellflower, with the smallest seed mass (0.3 mg), had the greatest mean dispersal distance (12 m), while Hazelwort, with the largest seed mass (4.5 mg), had the smallest (2 m).

DBellflower (0.3 mg) and Wood aster (0.9 mg) both traveled an average of 12 m, showing that a lighter seed is carried farther. Because both of those seeds landed at the very same distance, the pair looks like a neat illustration of the rule even though their masses are not far apart.
