D flip flops is nothing but delays or buffer flip flop so it's nothing to do with the inputs.

It's start from left to right ...and final output is 0 . (Right most bit)

Hence option B is correct.

Answer 1

D flip flop is act as wire ,it will return what we are given in input

in this question LSB,MSB are 0 so final output is 0

here we dont know about order of input

Option B 

Answer 2

D flif flop depend on next state (Qn+1=D).

So the final  input is the final output ..
