Final answer:
A resume summarizes employment and educational history. It, along with a cover letter, serves as a primary tool to market oneself to potential employers. A portfolio showcases a collection of work samples, especially useful in creative fields. The correct option is D.
Step-by-step explanation:
The document that summarizes employment and educational history is known as a resume. A resume is designed to provide a concise outline of a person's qualifications and experiences. It usually includes personal information, education, work experience, skills, and achievements.
A cover letter is an introductory document that accompanies your resume and highlights your suitability for the role, aiming to encourage the prospective employer to read your resume. Meanwhile, a portfolio is a comprehensive collection of documents and work samples that showcase your abilities and accomplishments, often used in creative industries or professions where tangible demonstrations of skill are beneficial.
Your resume and cover letter are your primary self-marketing tools and are essential for making a strong first impression. Your resume should be clearly formatted and, in most cases, limited to one page. It's also important to adapt your resume to suit the specific job you are applying for. An online portfolio, by contrast, offers a dynamic and accessible way for employers to review your work at their convenience.
