(A) Statement is true: Low temperature temporarily inactivates enzymes but preserves them.$(b)$ Statement is false: Enzyme activity decreases above the optimum temperature due to denaturation.$(c)$ Statement is true: High temperatures break the hydrogen bonds and other interactions,causing the enzyme to denature.$(d)$ Statement is false: Competitive inhibitors compete with the substrate for the active site of the enzyme,not with the product formed.Therefore,statements $(a)$ and $(c)$ are true.
