The complex number with modifying bar will be 12 - i so option (A) will be correct.
What is a complex number?
Complex numbers are helpful in finding the square root of negative numbers.
A complex number is the sum of a real number and an imaginary number.
The general form of a complex number is a + ib where the first part a called real and the ib is called imaginary.
If we solve x² + 1 = 0 ⇒ x = √(-1) which is called as iota(i).
Bar of complex number = replace i (iota) with - i (iota)
since z = 12 + i
So,
z bar = 12 - i
So 12 - i will be the correct answer to the given question.
