Correct answer
Explanation
CALLNAT is the correct Natural statement for invoking subprograms (also called external subroutines). 'Call' and 'Perform' are not valid Natural statements for this purpose - Natural uses specific keywords like CALLNAT, FETCH, or CALL for different types of module invocations. CALLNAT specifically calls Natural subprograms that are compiled separately from the calling program.
