The correct answer is: A. sentence capitalization
A button’s caption is entered using sentence capitalization. This means that the first letter of the first word is capitalized, as well as the first letter of any proper nouns. For example, the caption for a button that opens a new window might be “Open New Window.”
Book title capitalization is used for the titles of books, articles, and other long works. Character capitalization is used for the names of characters in stories, plays, and other works of fiction. Word capitalization is used for the names of things that are not proper nouns, such as “dog” or “house.”
