Being "on time" in business situations generally means being about "five minutes early".
Option: B
Explanation:
Either in business or in any government sector being on time is one of the key to grab best opportunity. Here in business being on time means atleast 5 minute early on the spot, if someone became late than with apology it is acceptable only upto 5-10 minutes immediately after a start. While the one who is late more than 15 minute they need to inform coordinators or head through phone call or text and with reason. Reaching too early also may become boring and non-interest sometimes, especially when meeting starts.
