Answer: 2. When the room is clear, let's get organized and plan the meeting.
Explanation: If you analize both options, on the first option: "1. When the room has been cleared, we need to develop an agenda for the meeting" the part where it says "develop an agenda" is using a more formal language by describing specific actions rather than just saying "get organized" as it is on the second one.
The sentence that sets an informal tone is:
"When the room is clear, let's get organized and plan the meeting." (Option B).
What is an informal tone?
An informal tone is one that is void of formalities or that does not use official language.
The second option has an informal tone because the first is more definitive and instructive while the other is more collaborative, hence informal.
