C Correct answer
Explanation

The TRACE instruction in REXX is used for interactive debugging and program execution tracing. When TRACE is enabled (with options like TRACE ALL, TRACE RESULTS, TRACE INTERMEDIATE), REXX displays each instruction before execution and/or shows intermediate results, making it easier to debug logic errors and trace program flow. DEBUG is not a REXX keyword, and EXPOSE/INTERPRET serve other purposes.
