Which of the following statements are correct? \n1. A flip-flop is used to store 1 bit of information. \n2. Race-around condition occurs in a J-K flip-flops when both the inputs are 1. \n3. Master-slave configuration is used in flip-flops to store 2 bits of information. \n4. A transparent latch consists of a D-type flip-flop
- A. 1, 2 and 3
- B. 1, 3 and 4
- C. 1, 2 and 4
- D. 2, 3 and 4
Answer: C. 1, 2 and 4
Explanation: Statement 1 is correct (a flip-flop stores 1 bit). Statement 2 is correct (toggling continuously during the high clock level causes race-around). Statement 4 is considered correct in standard multiple-choice contexts (a D-latch is transparent). Statement 3 is incorrect; a master-slave configuration still stores only 1 bit, but prevents the race-around condition.
