Quick replies for the chatbot

I am trying to create a chatbot. I am totally new into chatbots. I want to know how to create ‘Quick-reply’. Like: 3 options A,B,C . If I click on A I get a response relevant to A only. As far I have read the documentation of RASA CORE, I think this can be done by setting slots and buttons. As I am totally new I am not able to code it. Please help me
