Answer:
I believe the answer is B: decrease; males as they age.
Explanation:
Ok, don't hate me if I'm wrong!!!!!!
The graph only shows the gender and that they decrease as time goes on, it doesn't show that they are infant of grown or anything like that, so I know for a fact that it is not A or D. The graph shows both females and males decreasing as they get older. However, males decrease by more, so I believe the answer is B: decrease; males as they age.
It would be SUPER-DUPER FANTABULOUS if I could get brainliest!!!!!!
