Which of the following statements are correct ?

1. A flip-flop is used to store $1$ bit of information.

2. Race-around condition occurs in a $J$-$K$ flip-flop when both the inputs are $1$.

3. Master-slave configuration is used in flip-flops to store $2$ bits of information.

4. A transparent latch consists of a $D$-type flip-flop.

  1. $1$,$2$ and $3$
  2. $1$,$3$ and $4$
  3. $1$,$2$ and $4$
  4. $2$,$3$ and $4$

1 is correct

4 is correct

2 is correct (when j =1  k = 1 and clk = 1; Q output will toggle as long as CLK is high.Thus the output will be unstable creating a race-around problem with  this basic JK circuit.)

3 is incorrect(we can store 1 bit of information also)

Hence C option is Correct
