Is a "choice" the result of choosing or something to choose from?

If I have to choose between three things, do I have three choices? I have always thought of a "choice" as being either the act of choosing or the result of said choosing, but not one of the options from which to choose.

If someone tells me I have two choices, I tell them "No, I have one choice. I have two options." Am I right?

Solution 1:

The Merriam-Webster dictionary says both:

choice
1 : the act of choosing : selection <finding it hard to make a choice>
2 : power of choosing : option <you have no choice>

Solution 2:

If I have to choose between three things, do I have three choices?

Yes, in my experience "choice" is widely used in this context.

I have always thought of a "choice" as being either the act of choosing or the result of said choosing, but not one of the options from which to choose.

Really? If I google for "you have three choices" I find 700,000 results.

If someone tells me I have two choices, I tell them "No, I have one choice. I have two options." Am I right?

I'm not familiar with this particular rule, but it sounds like pedantry to me, especially since the way you frame the question makes it seem like many people are saying "choice" rather than "option" to you, and so you must already be aware that "choice" meaning "option" is a common usage.
