The sloth and coati populations would increase if most of the boa constrictors in the ecosystem were to die due to an illness. So, the correct option is B.
What do you mean by Ecosystem?
An ecosystem may be defined as the place or area where members of different species or communities live and interact with one another in response to food, shelter, and space.
When the population of boa constrictors died due to illness, the predator of sloth and coati is eliminated from the ecosystem. Hence, these species get a chance to survive and reproduce in the environment freely.
Therefore, the correct option for this question is B.
