What does the half circle on the clock input of a J-K flip-flop mean?(

1.	What does the half circle on the clock input of a J-K flip-flop mean?(a) Level enabled(b) Positive edge triggered(c) negative edge triggered(d) Level triggeredI had been asked this question during an interview for a job.I would like to ask this question from Triggering of Flip Flops in portion Flip-Flops of Digital Circuits
Answer» The correct option is (d) Level triggered Easiest EXPLANATION: The HALF circle on the clock input of a J-K flip-flop mean level triggered. WHEREAS the PRESENCE of TRIANGLE symbol implies that the flip-flop is edge-triggered.
