The correct choice is (a) Yes

To explain: The PROGMEM Utility can be used with non-static variables provided they are defined outside any function, i.e. they are defined globally. Conversely if one needs to work on a variable that is not defined globally then they would need to convert that variable into a static variable in order to use the PROGMEM Utility.
