The correct answer to the question "Letters that please the receiver are called" is d. good-news letters.

Explanation:

Good-news letters are a type of correspondence specifically designed to convey positive information or updates that are likely to please the recipient. This can include notifications of achievements, such as a job promotion, acceptance into a program, or other forms of congratulatory messages. The intention behind good-news letters is not only to inform but also to enhance the relationship between the sender and the receiver by sharing joyful news.

In contrast, the other options do not carry the same connotation.

• a. yes letters typically refer to correspondence that affirmatively responds to something previously discussed.
• b. routine letters are usually standard communications that do not carry emotional weight or significant news.
• c. invitation letters are used to invite someone to an event but do not inherently imply good news or positive content.

This distinction makes good-news letters particularly impactful in personal and professional relationships, reinforcing positivity and goodwill.
