Which of the following is NOT a part of a business letter?

In the context of a business letter, the standard components typically include the return address, body, salutation, and closing elements. The return address identifies the sender's location and is crucial for correspondence. The body contains the main message and purpose of the letter. The salutation is the greeting that addresses the recipient appropriately.

Meeting minutes, on the other hand, are a separate type of document that summarizes the discussions, decisions, and actions taken during a meeting. They do not fit into the structural format of a business letter, which is specifically designed for formal communication between parties, focusing on conveying specific information in a straightforward manner. Therefore, recognizing that meeting minutes do not belong to the standard components of a business letter is key to understanding the correct answer.
