Which is NOT a correct statement about the call stack? Select one: a. The reason return addresses are saved on a stack is that we only need access to the return address of the most recent call b. The call stack allows access to any return address on the stack c. The call stack can be used to save registers that a procedure needs to use d. The call stack holds return addresses e. The call stack allows access only to the top return address on the stack

Which statement about the trap instruction is NOT true? Select one: a.
