ABecause digital electronics have two states: ON and OFF

BBecause it is easier to write numbers with two digits

CBecause computers cannot understand more than two digits

DBecause binary numbers are shorter than decimal numbers

Step-by-Step Solution

Solution:

Step 1: Understand the basis of binary system in electronics
Digital electronics use two states: ON (1) and OFF (0).
Step 2: Connect binary digits to electronic states
Binary digits 0 and 1 represent these two states, making it reliable for computers.
