a. Decreasing plasma levels will not occur as inhibition decreases enzyme activity leading to slower elimination of drugs. 

b. Increasing plasma levels will occur due to slower elimination of drugs. 

c. No effect will not occur as inhibition decreases enzyme activity leading to slower elimination of drugs.
