What is an advantage of using Excel’s built-in templates to create invoices?

a The setting and data heading are already made and the data just needs to be inserted.
b A built-in template cannot be modified in any way, so the file’s look will be consistent.
c Only one invoice template is available, so it will be easy to learn how to use a template.
d Templates take a lot of time to set up initially, but then they save time for future applications.
