Step-by-step explanation:
The correct answer is option 1) Only business days (Mo-Fr).
When calculating timeframes or deadlines, typically only business days are considered. Business days refer to Mondays through Fridays, excluding weekends and public holidays. This is because most businesses and institutions operate on a Monday to Friday schedule.
For example, if a project is due in 5 business days and it is currently Wednesday, the deadline would be the following Wednesday, taking into account the weekends and excluding any public holidays.
