How can I make The gray option that can’t click?

I want to use as ‘Never a chance you can unlock it ,it’s a fake choice’
and as ‘you need to know that choice is existed so work better next time’

Ps. Sorry for my poor english ,i didn’t plan to make game in English… don’t worry lol
Ps2. Thank you in advance.
