Solution (By Examveda Team)

This question asks about a MySQL command that selects data from a table called employee. Let's break down the command:
`SELECT *`: This part tells MySQL to select all columns from the table.
`FROM employee`: This part tells MySQL to get the data from the table named employee.
`WHERE (title=’HEAD TELLER’) OR (start_date>2013-01-24)`: This part acts like a filter. It tells MySQL to only include rows that meet at least one of these conditions:
* `(title=’HEAD TELLER’)`: The title column in the row must be equal to 'HEAD TELLER'.
* `(start_date>2013-01-24)`: The start_date column in the row must be greater than 2013-01-24.
So, the correct answer is Option B**: All columns but only those rows which contain 'HEAD TELLER' as a "title" OR start_date are greater than 2013-01-24.
Important Note: This command will show all the rows where the title is 'HEAD TELLER' even if the start_date is less than 2013-01-24. It will also show the rows that have a start_date greater than 2013-01-24 regardless of the title.
