Which statement accurately describes the impact of using correct spelling and grammar?

• A. They have little effect on reader trust.
• B. They primarily affect the length of the report.
• C. They contribute to professionalism and clarity.
• D. They are optional in formal reports.

Answer: (C)

Good spelling and grammar matter because language quality directly influences how professional a report appears and how easily readers understand the content. When the writing is correct, it signals care, credibility, and attention to detail, which helps readers trust the information and focus on what the report is saying. Mistakes, on the other hand, can distract readers, lead to misinterpretation, or undermine the perceived seriousness of the findings.

The other ideas don’t fit: spelling and grammar do affect reader trust, they’re not mainly about the length of the report, and they aren’t optional in formal reports.
