What is a close synonym for 'anxious' in formal writing?

• A. Nervous
• B. Apprehensive
• C. Anxious
• D. Worried

Answer: (B)

In formal writing, aim for a word that preserves the sense of concern but keeps a restrained tone. Apprehensive fits perfectly because it conveys unease about something that might happen, without the stronger emotional edge or casual feel of other options. The word suggests a careful, measured worry appropriate for professional or academic contexts. For example, saying someone was apprehensive about the outcome communicates concern in a formal way. Nervous often implies physical tension or a more casual sense of fear; worried is clear but less formal; anxious can be direct and strong, which isn’t as suitable for a formal tone.
