You CAN call an OS/VS COBOL program from a VS COBOL II program in non-CICS environments (batch, TSO). The runtime handles the compatibility. However, in CICS environments, there are additional constraints and compatibility issues that make this difficult or not recommended. Option A correctly identifies that it's possible in non-CICS contexts. Option B is wrong because it's not absolute - the limitation is CICS-specific, not universal.
