Which keyword is used to create a database?

Answer: Option A

This question asks about how to create a new database in MySQL.
Think of it like building a new storage container for your data.
We need a special command to tell MySQL to make this new container.
Out of the options, only one is used to create things:
CREATE is the keyword used for making new things in MySQL.
So the answer is Option A: CREATE.
The other options are not used for creating databases.
SET is for changing settings, SETUP isn't a MySQL keyword, and LINK is for connecting to existing databases.
