The NumberFormat class uses factory methods to construct objects. The new operator is called implicitly in this case. The factory method that is used is called getPercentInstance(). Therefore choice c is correct. Choice a and Choice b are incorrect since they call the new operator explicitly. Choice d is incorrect because there is no PercentNumberFormat class that can be called with the new constructor.
