The contact information includes which details?

• A. The recipient's mailing address
• B. The sender's job title
• C. The company mission statement
• D. The mailing address, email address, and phone number of the sender

Answer: (D)

Contact information tells the reader how to reach the sender. In professional communications, it includes ways to contact the person, such as a mailing address, an email address, and a phone number. This full set is exactly what the option lists, making it the best answer because it provides multiple practical routes to get in touch. The recipient's mailing address isn't the sender's contact info, so it doesn't serve that purpose. The sender's job title isn't primarily contact information, and a mission statement describes purpose rather than how to be reached, so neither of those fit as the overall contact details.
