When COND is placed on an EXEC that calls a procedure, it applies to ALL steps in that procedure (B is true). COND can check multiple previous steps' return codes using EVEN/ONLY syntax, and stops at the first true condition (D is true). Option A is false because COND tests whether to SKIP the step. Option C is false because COND can also test abend conditions (abend codes), not just return codes.
