Option A is the right answer.
The AS SQL clause is used change the name of a column in the result set or to assign a name to a derived column. The renaming is a temporary change and the actual table name not change in the database.

There are different clauses and tools that are used to modify columns and rows in order to edit tables as you need. Each has a precise function and as the names aren’t self-exploratory, you need to learn their uses in order to work them properly. Not only this, you may need to practice them thoroughly as well.

For instance, the AS SQL clause is a special tool that is used to change the name of a column in the result set. It can also be used to give heading to different columns in order to ensure optimal editing and performance.
