Explanation
TIME=1440 in JCL specifies 1440 minutes (24 hours), which is the special value meaning NO time limit. It does NOT set a literal 1440-minute limit - that value removes time constraints entirely. Option B correctly states that no CPU time limit is applied.
AI explanation
In JCL, the TIME parameter normally sets a CPU time limit for a job step in minutes and seconds (MM,SS). The special value TIME=1440 is a reserved convention meaning no CPU time limit is enforced on that step, letting it run indefinitely rather than being killed after 1440 minutes.
