You are in a cinema hall watching a movie, you see a snake in front of your leg, you will -

The correct choice is: Remain cool, warn others, notify the hall authorities.

In a crowded hall panic can cause a stampede. The best action is to stay calm, warn people nearby and inform the staff who can deal with it safely: ‘Remain cool, warn others, notify the hall authorities.’

Shouting creates panic, and picking up the snake yourself is dangerous.

Hence the answer is ‘Remain cool, warn others, notify the hall authorities.’
