choice, option, alternative

choice, option, alternative

Teachers, could you explain the difference among them? Also, could you give one or more substitutes for each of them, if there are any? thanks!

An option is one thing which can be chosen from a set of possibilities. When you have chosen one of the options, that is your choice. If you are not happy with that choice, you can choose an alternative – an option different from the one originally chosen.

Also, alternative should imply that there are only two possibilities, while there can be any number of options, although many people use alternative where there are more than two. :D
