is a two digit number always less than a three digit number

Option C is correct. Whether a two-digit number is always less than a three-digit number depends on the first digit in the number.
A number can be a combination of a positive and negative integer. For example,
We can see from the numbers that 23 (a two digits number ) is greater than -230 (a 3 digits number) which falsifies the claim that a two-digit number is always less than a three-digit number.
The veracity of the claim all depends on the first digits of the number (whether it is a positive or negative integer)
