B Correct answer
Explanation

EJBContext.getCallerPrincipal() is the standard EJB API method to retrieve the caller's identity (as a java.security.Principal object) within enterprise bean code. This works in both session and entity beans. getIdentity(), getCallerIdentity(), and getUserId() are not standard EJBContext methods.
