One night after dinner, Alia went for a night walk. On her way back home, she stopped at the ice cream parlour nearby. When she was having ice cream, Dhamaka Singh kidnapped her and locked her in a room. There were three doors to get out of the room. The first door opens to a passage full of hungry crocodiles who haven't had food for two years, behind the second door is a room full of temperature-sensitive electric wires that may kill anyone and the third door leads to another room full of broken glass pieces. Which door is the safest for Alia to escape?
