Correct Response: A. A cover letter is your introduction to your prospective employer. The cover letter demonstrates your interest in the job, draws attention to your resume, and explains how your experience and skills relate to the position. The resume summarizes your experience, education, and skill set. A cover letter and resume should be personalized to the specific job posting to clearly illustrate how and why your skill set is aligned with the company's needs. Sending details about an offer made by another company would be considered impolite and will be detrimental to your job search (B). A reference is typically a supervisor or former teacher who can talk about the quality of your work and your work habits. It is not necessary to use a different set of references, since they provide more general information about your character and work ethic (C). A cover letter is supposed to describe why your knowledge and skills are a good fit for the position. Including information about other companies is off-topic and could be viewed as impolite (D).
