How to offer choices to the player (variable name)

Hello
I'm struggling because in my story I'd like to offer choices to the player.
I want the player to choose the name of his/her friend, but instead of asking the player "what's your friend name?"
I want to make proposal such as
"Your friend is :
John
Alex
Mark"

If anyone can help me I can't find the solution anywhere....


Thank you so much!!
