Which of the following letter formats uses indented paragraphs?

The semi-block letter format is characterized by its use of indented paragraphs, which adds a formal touch to the appearance of the correspondence. In this format, the first line of each paragraph is indented, producing a neat and organized look. This style effectively distinguishes it from the full-block letter, where all text is aligned to the left without any indentations, and the modified block letter, which has some elements aligned to the right but typically does not use indents for paragraphs. The simple letter format can vary significantly but tends not to adhere to the specific structure of paragraphs, focusing instead on straightforward communication. Understanding these distinctions helps recognize the semi-block format's unique style in professional correspondence.
