Option B is correct because the syntax is correct-using both names (the enclosing class and the inner class) in the reference declaration, then using a reference to the enclosing class to invoke new on the inner class. Option A, C and D all use incorrect syntax. A is incorrect because it doesn't use a reference to the enclosing class, and also because it includes both names in the new. C is incorrect because it doesn't use the enclosing class name in the reference variable declaration, and because the new syntax is wrong. D is incorrect because it doesn't use the enclosing class name in the reference variable declaration.
