Replying to If you were drowning...

So im a lil drunk and casino royal is on, theres a scene where a chick is stuck underwater in an elevator, heres the question.


If you were in a situation where you were 100% going to drown and there was no escape (think trapped in a room filling with water) would you-


A- Take huge gasps of water in order to try and make the suffering minimal and end it quickly

B- Hold your breath as long as possible, last a minute or so and eventually take a huge breath of water
