Final answer:
A 'Style' is a grouping of text formatting options that can be applied to text all at once, including font, paragraph alignment, and spacing. The correct option is 2.
Step-by-step explanation:
The grouping of text formatting that can be applied all at once is known as a Style. A Style may include various formatting options such as font size and type, paragraph alignment, spacing, indentation, and more.
For example, in business letters, block formatting is used to apply a uniform style to the entire document, which includes left-justifying the text, using single spacing within paragraphs, and double spacing between paragraphs without indenting.
Similarly, when writing essays or reports, paragraphs and sections are formatted to enhance readability and coherence, using Style settings to apply consistent text space, alignment, and font settings. The correct option is 2.
