Which of the following option is most suitable for flip flopa.with two stable states that can be used to store binary data.b.fundamental building blocks of digital electronics systems used in computers, communications, and many other types of systems.c.Both (a) and (b)d.It can be implemented using NAND gates only

The most suitable option for flip flop is c. Both (a) and (b). This is because a flip flop does have two stable states that can be used to store binary data, making option a correct. It is also a fundamental building block of digital electronics systems used in computers, communications, and many other types of systems, making option b correct as well. Therefore, both statements are true, making option c the most suitable choice. Option d is not necessarily true as flip flops can be implemented using other types of gates as well, not just NAND gates.
