Solution (By Examveda Team)

This MySQL command is asking the database to select specific information from the 'employee' table. Let's break down what each part does:
`SELECT emp_id,` This tells the database to retrieve the values from the column named 'emp_id'.
`‘ACTIVE’ AS STATUS,` This creates a new column named 'STATUS' and assigns the value 'ACTIVE' to all rows. In simpler terms, it's adding a column that will always show "ACTIVE."
`emp_id * 3.14 AS emp_pi,` This creates a new column named 'emp_pi' and multiplies the value of 'emp_id' by 3.14 (which is approximately pi) for each row.
`UPPER (lname) AS last_name` This creates a new column named 'last_name' and converts the values in the 'lname' column to uppercase letters.
`FROM employee;` This tells the database to retrieve data from the 'employee' table.
So, what will be the result? The command will create a new table with the following columns:
* emp_id - The original values from the 'emp_id' column.
* STATUS - All values will be 'ACTIVE'.
* emp_pi - The 'emp_id' values multiplied by 3.14.
* last_name - The 'lname' values in uppercase.
Therefore, the correct answer is Option B: emp_id, Status, emp_pi, last_name
