You're best answer to this would probably be "Choices A & C." Spelling errors, especially with seemingly small words, can lead an employer to believe that an applicant may have a lack of education or awareness. Of course, addressing the correct audience would be a major factor as well. For example: you would more ham likely not address a prospective employer the same way you would address your favorite cousin. Employers do however like to see you resumé completed in its fullest and, if applicable, have a few extra details worth sharing. Hope this helped !
