One way that young orangutans acquire foraging skills is through a behavior scientists call peering—closely watching older orangutans as they engage in an activity that the young have not yet mastered. Since female orangutans typically remain in the same area from youth through adulthood and males do not, Beatrice Ehmann and her colleagues hypothesized that it is more advantageous for immature females than males to devote attention to orangutans who are permanent residents of the immature individual's home region, and this should be reflected in sex-specific differences in peering behavior.
Which choice best describes data from the table that support Ehmann and colleagues' hypothesis?
Individual 6 and individual 1 directed a higher proportion of peering events at permanent residents of their home regions than did individual 13 and individual 15.
A
The proportion of peering events directed at permanent residents of the immature orangutans' home regions ranged from a low of 0.00 to a high of 0.67.
B
Individual 6 directed a higher proportion of peering events at permanent residents of its home region than did individual 1, and individual 13 directed a higher proportion of peering events at permanent residents of its home region than did individual 15.
C
Individual 13 engaged in 27 peering events, more than either individual 6 or individual 1.
