Which type of flip-flop has a clock input and a data input?a.J-K flip-flopb.SR flip-flopc.T flip-flopd.D flip-flop

To determine which type of flip-flop has a clock input and a data input, let's analyze the options provided:

1. J-K Flip-Flop: This flip-flop has two inputs (J and K) and a clock input. It can toggle its state depending on the inputs but isn't characterized primarily by a single data input.

2. SR Flip-Flop: The SR flip-flop has two inputs (Set and Reset), along with a clock input. It doesn't use a dedicated data input.

3. T Flip-Flop: The T (Toggle) flip-flop has a clock input and a single toggle input, which determines whether to toggle its output state, hence lacking a specific data input.

4. D Flip-Flop: The D (Data) flip-flop has a clock input and a single data input. The output state of the D flip-flop follows the data input at the moment of the clock's edge.

Final Answer

d. D flip-flop has a clock input and a data input.
