Which option enables multiple-statement execution?

Answer: Option A

This question asks about a setting in MySQL that allows you to execute multiple SQL statements in a single query. Imagine you have a set of tasks you want the database to perform, like inserting new data, updating existing data, and deleting some old data.

You want to do all of this with just one command. That's where the "multiple-statement execution" setting comes in.

Out of the given options, only one is correct. Let's break down why:

* Option A: CLIENT_MULTI_STATEMENTS - This is the correct answer. It's a specific client option in MySQL that allows you to run multiple statements within a single query.

* Option B: CLIENT_STATEMENTS_MULTI - This option is not a valid setting in MySQL.

* Option C: MULTI_STATEMENTS_CLIENT - This option is also not a valid setting in MySQL.

* Option D: MULTI_CLIENTS_STATEMENTS - This option is not a valid setting in MySQL.

Therefore, the answer is Option A: CLIENT_MULTI_STATEMENTS.

Remember, enabling multiple-statement execution can be helpful for efficiency, but it's important to use it cautiously and understand its implications. You can learn more about it in the MySQL documentation.
