The AUTO_INCREMENT sequences normally begin at . . . . . . . .

Answer: Option B

This question is about how MySQL handles AUTO_INCREMENT columns, which automatically assign unique numbers to each new row in a table.

Think of AUTO_INCREMENT like a counter that starts at a specific number. We need to figure out where that counter begins.

The correct answer is Option B: 1.

By default, MySQL sets the starting value of the counter to 1 for AUTO_INCREMENT columns. This means the first row you add to the table will have a value of 1 in the AUTO_INCREMENT column, the second row will get 2, and so on.

Here's why the other options are incorrect:

* Option A: 0 - AUTO_INCREMENT usually doesn't start at 0.
* Option C: -1 - AUTO_INCREMENT usually starts with positive numbers.
* Option D: 2 - While you can change the starting value of AUTO_INCREMENT, the default is 1.

Remember: AUTO_INCREMENT is a helpful tool for automatically managing unique IDs in your database.
