What typically characterizes a full-block business letter format?

A full-block business letter format is characterized by all paragraphs being left-aligned and not indented. This style promotes clarity and simplicity, making the letter easy to read and more professional in appearance. The left-aligned format means that every line of text starts at the left margin, providing a clean, organized look.

This format is widely used in business communications because it avoids the visual clutter of indents and enhances the overall flow of the document. By not indenting paragraphs, the reader can focus more on the content without becoming distracted by varying indentations.

Using bullet points, indenting paragraphs, or adding horizontal lines would introduce unnecessary complexity or alter the format of a full-block business letter, which thrives on straightforwardness and directness.
