Answer
Brief Explanations:
The sentence is about a prediction for the future ("in years to come"). The verb should be in a form that fits a prediction of future action. "Predict" is followed by a clause with a verb that can express future likelihood. Option A "decrease" (base form, used in predictive contexts with "predict" + that - clause, where the verb can be in present tense for future prediction in some cases, or here as a simple form to show the predicted action) is appropriate. Option B "have decreased" is present perfect, which refers to past - up - to - now actions, not future predictions. So the correct choice is A.
Answer:
A. decrease
