Which of these values is not valid as an AUTO_INCREMENT value?

Solution (By Examveda Team)

This question is about AUTO_INCREMENT in MySQL. AUTO_INCREMENT is a special feature that automatically assigns unique, increasing numbers to a column in your database table.

Think of it like a counter that starts at a specific number and goes up by one each time a new row is added.

The question asks which value can't be used as a starting point for this counter. Let's look at the options:
* Option A: 0 - This is not a valid starting value for AUTO_INCREMENT. It has to be a positive integer (whole number greater than zero).
* Option B: 1 - This is a perfectly valid starting value for AUTO_INCREMENT.
* Option C: 2 - This is also a valid starting value.
* Option D: 3 - This is valid too.

Therefore, the correct answer is Option A: 0.
