Hi Cici,
Choice can be turned into a very - to choose. However, option is always a noun, you would have to say, I chose that option, or I picked that option, or I had that option.
Also, I think choice is used more for casual, everyday things. For example,
I have a choice between two apples.
I chose to wear black pants instead of white pants.
Option is more often used when talking technically, like
I have the option of buying or leasing my car.
I want the option of being able to refund it.
But the two are pretty similar!
