A convenient feature used when proofreading a document?

• A. Spell-check
• B. Grammar-check
• C. Auto-correct
• D. Thesaurus

Answer: (A)

Focusing on correct spelling is essential in proofreading because it directly ensures clarity and professionalism. A spell-check tool scans the document for misspelled words, underlining or highlighting them and offering likely corrections, which makes catching typos quick and efficient. This is the most convenient way to sweep through the text and fix errors before moving on to deeper edits. Grammar-check helps with sentence structure and punctuation, auto-correct can change text automatically and may introduce unwanted changes, and a thesaurus aids word choice rather than spelling. So for a fast, reliable pass to catch spelling errors, this feature is the best choice.
