I believe your question is one about typing style. A full block or complete block is a typing style that places everything on the page on the left, including addresses, date, and signature. If you need to indicate a new paragraph, just click enter twice, which will leave one blank line indicating a paragraph break.
Block format means that all of the paragraphs are flushed left. With block format you will not have to indent your paragraphs.
The main formats for letter writing are block format, modified block format, and semi-block format. In block format, all text is left-aligned with single spacing except for double spacing between paragraphs. Modified block format is similar but has the date and closing aligned to the right. Semi-block format is a less common variant where the paragraphs are indented instead of being left-aligned.

Block Format
The three main formats of business letters are the block format, the modified block format, and the indented format. In the block format, all text is aligned to the left margin with no indentation. The modified block format has the sender's address and date aligned to the right, while the rest of the letter is left-aligned. The indented format features indented paragraphs, with the sender's address and date typically aligned to the left.
ÒThe modified block letter format is usually used for personal letters and informal business correspondence.
The format that does not indent any section of a business letter is the b block format. In this style, all text is aligned to the left margin, including the date, address, salutation, body, and closing. This creates a clean and uniform appearance without any indentations.
The full block format does not indent.
Heading, Body, and Closing
Heading, body, and closing
the answer is A.
I say that the full block format for a business letter is the most convenient to format. All of the information in the letter is justified to the left margin.
