Question 2 MSQ · 4.0 marks

Which of the following statement(s) is/are true regarding activation records used during function calls?

An activation record is removed from the stack immediately after a local variable is declared.
Local variables of a function are typically stored inside its activation record.
A return address is stored in the activation record so that control can return to the caller after the execution of the called function.
All activation records in the stack correspond only to recursive function calls.
When a function calls another function, the control link in the callee's activation record points to the activation record of the caller.
