C.
All of the mentioned
D.
None of the mentioned

Answer: Option A

Solution

Answer: Option A
Solution:
This MySQL statement is used to retrieve information about employees from a table called "employee".
Let's break down the statement:
SELECT emp_id, fname, lname FROM employee
This part selects the "emp_id", "fname" (first name), and "lname" (last name) columns from the "employee" table.
WHERE LEFT (lname, 1) =’F’
This is a condition that filters the results. Here's what it means:
* LEFT (lname, 1) : This function extracts the first character (1) from the "lname" column.
* = 'F': This compares the extracted character to the letter 'F'.
In simpler terms, the statement will only select those employees whose last name starts with the letter 'F'.
Therefore, the correct answer is Option A: Only those employees are selected whose last name started with 'F'.
