I think C is the correct answer.

a) c== container //NO (same expln as for ans b) )
b) c.equals(Class.Container) //NO , (first ,syntactically WRONG..)
c) c instanceof Container //YES
d) c instanceof Component //NO ,Container is a Component,BUT all Components are NOT Container
e) c implements Container //NO ,Container is a NORMAL CLASS
