Final answer:
b) 2 times
In a personal-business letter using block formatting, you should hit the enter key two times after the date to ensure proper spacing before the inside address.
Step-by-step explanation:
The question pertains to the correct formatting of a personal-business letter, specifically how many times the enter key should be hit following the date. In block formatting, which is the most common way to format a business letter, the text should be left-justified and single-spaced, with double spacing between each paragraph.
According to this guideline, after placing the date in the acceptable format and leaving a blank line, you should hit the enter key two times before proceeding to the inside address. This spacing creates a visual separation between the date and the rest of the letter, ensuring a clear and professional appearance.
