Which term means to cancel something out; to nullify?

• A. Mutual
• B. Negate
• C. Network
• D. Monotonous

Answer: (B)

The main idea here is finding a word that means to cancel something out or make it null. Negate fits perfectly because it means to deny, cancel, or render something invalid or ineffective. You can use it in sentences like: new evidence negates the previous conclusion, or the clause is negated by the latest ruling, meaning it no longer applies. The other options don’t carry that sense: mutual means shared between parties, network is a system of connections, and monotonous describes something dull or repetitive. So negate is the best choice for conveying canceling or nullifying.
