B Correct answer
Explanation

The COND parameter in JCL is used to test return codes from previous job steps before executing the current step. It allows conditional execution based on success or failure of prior steps. RC, CODE, and RETURNCD are not valid JCL keywords - COND is the standard mechanism for conditional step execution based on return codes.
