Attempted by 285 students.
Show answer & explanation
Correct answer: B
The SR (Set-Reset) flip-flop uses a feedback mechanism where the output is fed back into the input. This allows it to remain in a stable state even after the initial input signal is removed.
Set (S): Switches the output to 1.
Reset (R): Switches the output to 0.
Hold: If neither is activated, the circuit "remembers" its previous state.
