Build an Augmented Reality Unity Game

Hi, I've designed a game for children with augmented reality-assisted games. The game's scenes and characters are ready but I'm having trouble writing code. What I want is the code part written in c # to be fully compatible with vuforia and unity. In short, if I have to explain my game, it will consist of three levels and there will be three options against each character in each level. For example, if the character is a cow, choices will be herb, chops and ice cream, and a voice will be read in the manner of what the cow eats which one. After reading the question, the user will select one of three options. If the option is correct, it will play the correct sound and the next level screen will appear. The other level, which is locked, will be opened and passed. If it chooses the wrong option, the wrong tone will come and one of the player's three available lives will be reduced, but at the same time it will return to the level screen as in the correct option. I can send a more descriptive video of the game.
