Answer:
C. Neatness, business letter format, professional tone, attention to punctuation and spelling.
Explanation:
When applying for a job, you want to seem as professional and capable as possible. Your cover letter should be written on a white paper, neatly, following the format of a business letter (it should include your information, followed by a formal salutation, body of the cover letter written in paragraph form, closing, and your signature). Your tone should be professional, as you are entering a professional environment, and should not convey your personality. Attention to punctuation and spelling is very important, as literacy is just another proof of your education and capability.
