C because if if you have two species eating grass and half the total species dies, that'll result in more food for the remaining species, not less. :)
answer choice A would probably be least likely to happen.
The least likely outcome after a disease kills most of the rabbits in a meadow is that the mice will not have enough food (option C). With fewer rabbits, more plants will be available for the mice to eat. Therefore, the ecological balance often provides more food for remaining species after a decline in one population.
