Creating a chatbot that explains answers from a Q&A dataset

I’m trying to create a chatbot. I have 7,500 questions and answers. I want the chatbot to explain the answer and the wrong answers interactively.

What do you mean by “explain the answer and the wrong answers interactively” ?

The goal is that the chatbot would be able to explain the answer and explain why the other options are wrong, but by interactively I meant the students could ask questions to the chatbot for even more clarification.
