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 male orangutans typically leave the area of their birth upon maturity and females do not, Beatrice Ehmann and her colleagues hypothesized that it is more advantageous for immature males than females to devote attention to orangutans who are immigrants to the home region of the immature individual, 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?
The proportion of peering events directed at immigrants by immature orangutans of both sexes ranged from a low of 0.00 to a high of 1.00.
A
Immature male individual 10 directed a lower proportion of peering events at immigrants to their home regions than did individual 8 and individual 19.
B
Individual 8 directed a higher proportion of peering events at immigrants to its home region than did individual 10, and individual 6 directed a higher proportion of peering events at immigrants to its home region than did individual 4.
C
Individual 10 had the highest total number of peering events observed at 33.
