Depending on your teacher or the interpretation of this question, the answer could be C or D. A letter of application literally implies that you are outlining your qualifications for a particular position and applying for the job at the same time. That would make the correct answer “C”. If it is not truly a letter of application but a transmittal letter or cover letter, then it would state something to the effect: “In response to the job posting for research assistant (or whatever job you are applying for), I am enclosing my resume. My experience with computer applications and technology as well as my laboratory credentials would make me a valuable addition to your staff….” Something like that would actually be considered a cover letter instead of a “letter of application”. So, if used in that way, D would be the correct answer. However, the use of “portfolio” is somewhat confusing. It implies that the subject is art or sales or other examples of your work. A resume outlines your skills, accomplishments and abilities and value and a true letter of application would be a resume.

How did your teacher teach the class? What was the context in which she used the phrase “Letter of Application”?

If it was truly a Letter of Application, accompanied by examples of your work (or a portfolio) then the letter would outline all your skills and accomplishments and qualifications for the job while the portfolio would validate your statements and/or give examples of your work.
