A. A non-competitive inhibitor
✓
B. A competitive inhibitor
C. A substrate analogue only
D. A coenzyme

📝 Explanation

Non-competitive inhibitors bind at sites other than the active site and can bind regardless of substrate occupancy. Competitive inhibitors require access to the active site. Concept tested: Binding characteristics of inhibitors.
