Solution

The correct option is B Open the doors and windows
When winds blow over a weak roof, it creates a low pressure over it and a high pressure inside causing the roof to be blown off. Opening the doors and windows reduces this pressure difference and avoids the roof from being blown off.
So, the correct answer is open the doors and windows
