Which is the best action to take during an earthquake?

B: If inside, seek protection from windows and hanging objects.

Explanation:

People should remain on their knees. As this position protects you from being knocked down, it also allows you at the same time to stay really low and crawl to some other place if needed. Head should be covered at all times. If there is a big desk, a person should cover underneath. In order to protect your vital organs, you should bend over as that position will keep them protected. Remain calm until the shaking stops. It is known that earthquakes, along with other catastrophes, always occur with no warnings, so you won't be able to run or crawl, that's why it's very important not to move, because you're most likely to get injured that way.
