What is the best explanation for why digital data is represented in computers in binary?
a. the binary number system is the only system flexible enough to allow for representing data other than numbers.
b. it's easier, cheaper, and more reliable to build machines and devices that only have to distinguish between binary states.
c. it typically takes fewer digits to represent a number in binary when compared to other number systems (for example, the decimal number system).
d. it's impossible to build a computing machine that uses anything but binary to represent numbers.

(B)  It's easier, cheaper, and more reliable to build machines and devices that only have to distinguish between binary states.

Explanation:

 The representation of the digital data in the computer system in the binary form because it is easier and cheaper to use in the system. It is more reliable to build the machine and the devices for distinguish the binary states.  

Computer basically uses the 0 and 1 binary digits for storing the data in the system. The computer processor circuits are basically made up of the various types of transistors that uses electronic signals for the activation process in the system.

The o and 1 are the binary digits that reflect the different states of the transistor that is OFF and ON state.

answerthe above statement is (true);
