Answer 3

In some other languages it starts at 1, but essentially the usual reason is because 0 makes more sense than 1 in computing when you bring binary into question.

0 is the smallest number that can represented in binary, therefore you save a bit by starting from 0. For example,

starting from 0 in binary:
0, 1, 10, 11, 100, 101, etc

starting from 1 in binary:
1, 10, 11, 100, 101, etc
