While researching a topic, a student has taken the following notes:
- Australian ecologist Alison Lullfitz studied the distribution of Platysace deflexa (youlk), a small shrub with edible tubers.
- Lullfitz found that youlk plants gathered at sites across southwest Australia had very similar DNA despite differences in soil conditions.
- Lullfitz hypothesized that humans had transported the plant throughout the region.
- Lullfitz consulted Shandell Cummings and Lynette Knapp, members of the area's Noongar Aboriginal group.
- Cummings and Knapp confirmed that their ancestors carried youlk when traveling across the region.
The student wants to explain Cummings and Knapp's contribution to Lullfitz's study. Which choice most effectively uses relevant information from the notes to accomplish this goal?
Lullfitz found that Cummings and Knapp had information relevant to her study of Platysace deflexa's distribution.
A
Cummings and Knapp confirmed that DNA sequences from the Platysace deflexa plants Lullfitz had gathered were in fact very similar.
B
Lullfitz consulted Cummings and Knapp, members of the Noongar Aboriginal group, who assisted with her study of Platysace deflexa, a small shrub with edible tubers.
C
By indicating that their ancestors transported Platysace deflexa, Cummings and Knapp provided information that supported Lullfitz's hypothesis.
D
