Which type of writing follows professional writing standards?

• A. Formal Letter
• B. Table of Specifications (TOS)
• C. Sentence Structure
• D. Adverb

Answer: (A)

Professional writing standards are best demonstrated by a formal letter. It follows a clear, conventional format that signals professionalism in business and official communications. The structure typically includes a header with addresses, the date, a formal greeting, a concise body that states the purpose and key details, a courteous closing, and a signature. Language stays respectful and precise, avoiding slang and informal phrasing, and punctuation and layout align with standardized expectations. This combination of purpose-driven content, audience-appropriate tone, and consistent formatting is what makes a formal letter the example of professional writing. Other items describe a planning tool for exams, a grammar concept, and a word class rather than a formal written document, so they are not examples of professional writing standards.
