What's the best "user input method" that will allow people to choose from a selection of variables and it out puts an answer?

Question

I need help with applying user input. Im building a app and I am trying to get users to select an option from a list of characters/variables . For example a Person select a "banana" and the output would be "A banana is yellow". How do I enable them to select options I provide and make it output an answer? Hope this make sense. (the banana has nothing to do with the app, its just an example). All help is appreciated.
