If the coefficient of relatedness between two individuals is zero (r = 0), then A) altruism can evolve if c b. B) altruism can evolve if c

Question

If the coefficient of relatedness between two individuals is zero (r = 0), then
A) altruism can evolve if c > b.
B) altruism can evolve if c < b.
C) altruism cannot evolve via kin selection.
D) altruism will sometimes evolve regardless of the values of c and b.

The coefficient of relatedness measures the genetic relatedness between two individuals. A value of zero means there is no genetic relatedness, and therefore no potential for kin selection to favor altruistic behavior. So, altruism cannot evolve via kin selection in this scenario.
