Answer: A. Specify an indent value in the Paragraph panel
Step-by-step explanation:
Katie's wants an indent for the first paragraph and for all subsequent paragraphs in case of section breaks in the chapter.
So in this case if we specify an indent value in the paragraph panel then it would appear in all the subsequent paragraph section.
Option b is not correct as using the tab key would be a long process and have to keep a count on the number of times the tab needs to be placed.
Option c is incorrect as pressing the space button would be more longer option and the indent would also be not at the same place where we want it.
The indent value would work for characters and would not work for paragraphs as desired by katie.
