Answer:
The answer is "Option a"
Explanation:
In the given question the correct answer is the option a because when we change decimal number 3 into a binary number, It will give "11". To know its decimal number we add both numbers.
for example:
binary to decimal (11)₂=?
∴ 2¹=2 and 2⁰=1
= 1×2¹+1×2⁰
∵ 1×2+1×1
=2+1
=3
and other options are not correct, that can be described as follows:
In option b, option c, and option d, The computer understands the only binary language, that contains only 0 and 1, and in these options, It contains other value, that's why it is not correct.
