OK, now it’s clear this is a homework/interview puzzle question.
A better way of writing the question would’ve been to say there are three base classes named red, green, yellow. Each class gets extended to three classes apple, banana, orange. You are not able to see the source code to know which of the three extended classes got extended from the three base classes. To solve the puzzle, you need to write a piece of code that compiles and runs without any errors and prints the three associations between base and extended classes.
Hint: a form of casting can be used to solve this puzzle.
