Which of the following combinations of gates can be used to make
a clocked SR flip-flop? Assume NOT gates have one input each, all
other gates have two inputs each. (One or more is true. Your answer
is considered correct only if all and only the true options are
selected.)
A. 4 NAND gates,2 NOR gates
B. 2 AND gates,1 OR gates,1 NAND gates,1 NOR gates
C. 1 NAND gates,4 NOR gates
D. 1 OR gates,4 NAND gates,7 NOR gates...
