Male grey langurs leave/are ejected from the single-male groups upon reaching reproductive maturity. This suggests that all infants living in a group are probably the offspring of the current single, dominant adult male. This restricted access to mates _______ the fitness of the lone male in the uni-male multi-female groups, and ______ the fitness of the males in the bachelor groups. A. increases, increases B. Increases, decreases C. decreases, decreases D. decreases, increases
