Inner class concept

[Shaili Merchant]

I came across this question in IBM mock test.
14)
Which of the following statements is true?

a) An interface can contain a nested top-level inner class.

b) An interface can contain a member inner class.

c) A member inner class can implement an interface.

d) A static method can contain a local class.

e) A static method can contain a nested top-level class.

My answer : b c d

Just wanted to confirm whether my answer is correct or not.
Thanks.

This question uses rather unusual terminology. There's no such thing as a "nested top-level class" or "nested top-level inner class"; these are basically self-contradictory terms.

However, if we assume that A and E are just referring to "static nested classes", then I believe the answer is A C D. Note that all member classes within an interface are implicitly static.

Thanks Kelvin..
I was doubtful between choosing option a and b only.
