Final answer:
Named method parameters are indeed stored in a call frame on the stack, which is crucial for maintaining the execution context of a method or subroutine in a program's runtime environment.
Step-by-step explanation:
The statement 'Named method parameters are stored in a call frame on the stack' is True. When a method is called in most programming languages, a call frame, also known as a stack frame, is created on the call stack. This call frame contains all the method's parameters, both named and unnamed, as well as local variables and other information necessary for the method's execution, such as the return address. The call stack is a critical component of a program's runtime environment, allowing for the tracking of each active subroutine or method and making sure that its execution context is maintained.
