A triggering takes place on the negative-going edge of the CLK pulse

B triggering takes place on the positive-going edge of the CLK pulse

C triggering can take place anytime during the HIGH level of the CLK waveform

D triggering can take place anytime during the LOW level of the CLK waveform

ANS:A - triggering takes place on the negative-going edge of the CLK pulse

As a bubble can be seen on input clock so trigerring will take place on the negative-going edge of the CLK pulse
