Inner classes are defined within outer classes and are only accessible from within the outer class. Therefore, to create an instance of an inner class from outside its outer class, we need to use the syntax of outerClass.innerClass to access and instantiate it. In other words, the outer class object is used to access the inner class and the .new syntax is used to instantiate it. Option A is incorrect as there is no special keyword required. Option D is incorrect as it is indeed possible to create an instance of an inner class from outside its outer class. Option B is incorrect as inner classes cannot be instantiated just like any other class as they are dependent on their outer class.
