A and B are the correct answers, an inner class can only have one level of inner class. A very sneaky question, got me having to look and research.

I believe the answer is A and D. You can have multiple levels of inner classes.

Malvika Jain - Jul 25, 2022

A & B are correct

Actually, the only correct answer is A. You must specify access modifier for outer class, though it's inner by default for inner class.

AB correct. Interfaces do not have access modifiers, they are global by default.
