Solution (By Examveda Team)

This MySQL command is designed to retrieve information from a table named "employee". Let's break down what each part does:

SELECT emp_id,
This part tells MySQL to select the column named "emp_id" from the "employee" table.

‘ACTIVE’ STATUS,
This part creates a new column named "STATUS" and assigns it the value "ACTIVE" for every row in the result set.

emp_id * 3.14 emp_pi,
This part creates a new column named "emp_pi" and calculates the value by multiplying the "emp_id" column by 3.14 (approximately the value of Pi).

UPPER (lname) last_name
This part creates a new column named "last_name" and converts the value in the "lname" column to uppercase.

FROM employee;
This part specifies that the data should be retrieved from the "employee" table.

Therefore, the final result will include the "emp_id", a new column named "STATUS" with the value "ACTIVE", a calculated column "emp_pi", and a new column named "last_name" containing the uppercase version of the "lname" column.

So the correct answer is Option B: emp_id, Status, emp_pi, last_name.
