Try C. a downward gravitational force exerted by Earth
The tropical rain forest is located mostly on Islands. Mainly found in Africa.
The force of gravity F_g will act downwards.
Normal force F_N will act upwards equal to the force of gravity.
A force due to uniform acceleration F_a will act upwards to move the elevator upwards.
Thus, figure E is the correct answer.
Scientific theory because it's a theory it's already an answer but it might change depending on the condition.
