when D will be 0 then in the first input to the lower nand gate will be 1 and the first input to the upper nand gate will be 0 If clock (CLK) = 1 then in the upper Nand gate 0 NAND 1 will be 1

and in the lower nand gate 1 NAND 1 will be 0.

now In the Second upper NAND gate 1 will go as the first input and the second input will be Q Complement ... Now what will be this Q complement or Q' 0 or 1 .. and Why ??
