Which conjunction is used to compare two different facts or situations; also: during the time that (more formal than 'while')?

• A. Whereas
• B. Whilst
• C. Although
• D. Meanwhile

Answer: (B)

Think about expressing that two actions happen at the same time with a formal tone. The word that fits is the one meaning “during the time that” and it links two clauses as a conjunction, signaling simultaneous events. That word is the British form of “while,” used in formal writing: whilst. For example, “Whilst she was presenting, the team recorded the results.” This shows timing and keeps a more formal register than “while.”

The other options serve different functions. For instance, the word that compares two different facts or situations by highlighting contrast is whereas, which is about comparison rather than timing. Although introduces a concession or contrast, not timing. Meanwhile signals something happening at the same time but as an adverb, not a conjunction linking two clauses.
