Recall that the introduction to chapter 11 (prosocial behavior) began with a description of several of the citizen-heroes of september 11, 2001-for example william wik, who refused to flee to personal safety because there were still people to be rescued. he died when a tower collapsed. wik was willing to sacrifice his own life to save others, and his behavior could thus best be described as
a) altruistic.
b) prosocial.
c) evolutionarily adaptive.
d) an example of kin selection.

a) altruistic.

Explanation:

According to my research on the answers provided for the question, I can say that based on the information provided within the question Wik's behavior could best be described as altruistic. This means that he showed extreme unselfishness, or a selfless concern for the well-being of others. Which is exactly what Wik was displaying when he sacrificed his life in order to save others.
