this introduces an applicant and the applicants résumé to a potential employer: a. personal goal statement…

Brief Explanations:

A cover - letter is a document that accompanies a resume and introduces the applicant and their resume to a potential employer, highlighting key qualifications and interest in the job. A personal goal statement is more about an individual's long - term goals and may not directly introduce the resume. A job application is a broader form that may include the resume but is not the document that specifically introduces the resume. A reference is a person or a document that attests to an applicant's character or work, not an introduction of the applicant and resume.

Answer:

B. Cover Letter
