What word means 'to limit'?

• A. retain
• B. restrict
• C. sublingual
• D. suppress

Answer: (B)

To limit means to place boundaries or rules that reduce how much or what can happen. The word that fits this idea most directly is restrict, because it specifically conveys setting limits or constraints. Retain means to keep something, not to limit it. Sublingual is a term about location or route (under the tongue), not about limiting. Suppress means to prevent or push something down, which can imply stopping completely rather than simply setting a boundary. So the best fit for “to limit” is restrict.
