NEW QUESTION # 43
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?

A. Declare the class as global and use the public access modifier on the method.
B. Declare the class and method using the global access modifier.
C. Declare the class and method using the public access modifier.
D. Declare the class as public and use the global access modifier on the method.

Answer: B

Explanation:
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. References:

* Global Modifier Accessing Public Elements in a Managed Package
