When using Open Punctuation in business letters, the correct responses would be:
- No punctuation in address block
- No punctuation used in the body of the letter.
- Greeting
- Punctuation in address block (note: this would typically be the exception; however, the main purpose here is to clarify what Open Punctuation relates to, focusing on other aspects).
In traditional Open Punctuation formats, the goal is simplicity and clarity, avoiding unnecessary punctuation marks, particularly in the salutation and closing sections. In this context, you typically wouldn't use punctuation in the closing or address areas. So while there may be nuances to how "punctuation in address block" can be interpreted, the key principles of Open Punctuation focus on minimizing punctuation throughout the letter itself.
Thus, the responses that most accurately represent Open Punctuation principles are:
- No punctuation in address block
- No punctuation used in the body of the letter.
- Greeting
- No signature block (if you interpret it strictly to mean that there's no punctuation in the closing parts).
Please choose based on your understanding and specific contexts.
