The correct answer is: D.Competition

Here's why:

When two bears are fighting over the same mate, they are competing for a reproductive resource (the mate). This is an example of sexual competition, which is a form of competition between individuals of the same or different species for access to mates.

Why the other options are not correct:

A.Predation involves one organism killing and eating another. Since the bears are not hunting each other, this is not an example of predation.
