By the truth table of D flip flop, we can observe that Q always depends on D.
Hence for every negative trigger pulse ,the logic at input D is shifted to Output Q.

d flip flop takes the -ve edge triggered if the input is low

Q depends on the value of D.

Point1:
FF is -ve edge triggered means the o/p will follow i/p only on transition of clock from 1 to 0.
It means that the o/p D=Qn=Qn-1 when clock changes from 1 to 0.

The o/p changes only at the -ve edge of clk.

Negative edge triggered is created with the help of D-flip flop and D depends on Q.

D stand for direct whatever will be the data at f/f it will transfer to o/p and on next clock it will transfer to next f/f, data will transfer directly on changing clock, f/f will respond according to -ve edge triggered clk in the same manner.

Can anyone tell me what's the relation between CLK triggering and output of the Off.

What was PGT?

An edge-triggered flip-flop changes states either at the positive edge (rising edge) or at the negative edge (falling edge) of the clock pulse on the control input. The three basic types are introduced here: S-R, J-K and D.
