The answer is c: 1 inch all around.
Explanation for each option:
a. .5 inches all around - This margin size is generally too small for standard documents, which typically require more space for readability and printing purposes.
b. Automatic setting in Microsoft Word - While this might seem convenient, the automatic setting can vary depending on the version of Word and the template being used. It does not guarantee a standard margin size.

d. 1.5 inches all around - This margin size is larger than the standard and is typically used for specific formatting requirements, such as when additional space is needed for annotations or binding.
In summary, the standard and widely accepted margin size for most documents is 1 inch all around, making option c the correct choice.
