Show answer & explanation
Correct answer: B
A D flip-flop (Data or Delay flip-flop) transfers its input directly to the output after a clock trigger. The characteristic equation is Qnext = D. This means whatever logic level is present at the D input will appear exactly at the output state Q on the next active clock edge.
Thus, the correct option is B.
