What is the maximum amount of characters you can use on a single twitter message? 140 160 200 300

None of the options seem to be correct since you can only use a maximum of 280 characters on a Twitter message. If you round it up though, the answer would be 300.

Hope it helped,

Happy homework/ study/ exam!
