What will be the result of the following MySQL command?

WHERE TITLE=’teller’ OR start_date=’2007-01-01’

This MySQL command is used to filter data based on specific conditions.
Let's break down the command:

WHERE TITLE=’teller’ OR start_date=’2007-01-01’

This command will select rows where either:

1. TITLE=’teller’ : The employee's job title is "teller."
OR
2. start_date=’2007-01-01’ : The employee's start date is January 1, 2007.

In simpler terms, it will fetch data about employees who are either tellers or started working on January 1, 2007.
Therefore, the correct answer is Option D: All of the mentioned.

This command will return data for employees who meet any of the following criteria:
* They are a teller.
* They started on January 1, 2007.
* They are a teller and started on January 1, 2007.
