Cloud Kicks Fitness, an ISV Salesforce partner, is developing a managed package application. One of the application modules allows the user to calculate body fat using the Apex class, BodyFat, and its method, calculateBodyFat(). The product owner wants to ensure this method is accessible by the consumer of the application when developing customizations outside the ISV's package namespace. Which approach should a developer take to ensure calculateBodyFat() is accessible outside the package namespace?
Correct Answer: D
The global access modifier declares that the class and method are known by all Apex code everywhere, not just within the same application or package namespace. This access modifier must be used for any method that must be referenced outside of the application, either in SOAP API or by other Apex code1. The other options are either incorrect or insufficient, as they do not guarantee the accessibility of the method outside the package namespace2.
