Final answer:
The alignment of text that is flush with both the left and right margins is called justified alignment. This creates a smooth edge on both sides of the paragraph, which is a common practice in professional document formatting. The correct option is A. Justified.
Step-by-step explanation:
When text is aligned so that both the left and right edges of the paragraph are flush with the left and right margins, this type of alignment is called justified.
Justified text provides a clean and formal look by ensuring that the text aligns perfectly along both the left and right edges, except for the last line of a paragraph which may be left-aligned if it does not fill the entire line. This is different from centered, left-aligned, or right-aligned text, where text is respectively aligned along the center, left margin, or right margin, creating ragged edges opposite the alignment. In professional document creation, such as in newspapers, books, or formal documents, justified alignment is a common choice as it gives a tidy appearance to large blocks of text.
In option A, Justified is the correct option for this type of text alignment. Option B, Centered, refers to text that is centered horizontally between the left and right margins. Left-aligned (Option C) text is aligned along the left margin, creating a ragged right edge, while Right-aligned (Option D) aligns text along the right margin, creating a ragged left edge. Therefore, the answer to the question is A. Justified.
