Animals often behave in certain ways that can increase their reproductive success. Read the passage about a specific animal behavior. Then, follow the instructions below.
Fifteen-spined sticklebacks are small fish that live in the northeastern Atlantic Ocean. Male sticklebacks build nests for their eggs. Then, the males mate with multiple females. After a male mates with a female, she lays eggs in the male's nest and then leaves. The male guards his nest until the eggs hatch. As he guards the nest, he waves his fins near the eggs for short periods of time. This behavior is called fanning.
By fanning his nest, a male stickleback can help bring fresh water and nutrients to the eggs. The more frequently a male fans his eggs, the more eggs hatch.
Why might fanning eggs increase the reproductive success of a male fifteen-spined stickleback? Complete the claim below that answers this question and is best supported by the passage.

Fanming eggs increases the chance that.

A: The male will build a nest for female to lay eggs in.
B: The male will spend more energy while waving his fins.
C: The male's offspring will become adults.
