Answer:
B. certifications
Step-by-step explanation:
The correct answer is B. certifications. Certifications are typically listed on a resume rather than included as separate documents in a career portfolio. A career portfolio typically includes items such as a resume, cover letter, samples of work or projects, reference letters, and evidence of skills and accomplishments. Certifications are usually mentioned in the resume's education or skills section rather than included as separate documents in a portfolio.
