Here!

<h2>The answer is Option A!</h2>

(x + 2 \sqrt{3} i)(x - 2 \sqrt{3}i )

<h3>Why so??</h3>

Let's see what complex numbers are!

(x + 2  \sqrt{3 }i  )(x - 2 \sqrt{3}i ) \\  =  {x}^{2}  - 2 \sqrt{3} x + 2 \sqrt{3} x -  {(2 \sqrt{3} i)}^{2}  \\  =  {x}^{2}  -  {(2 \sqrt{3}i) }^{2}

Now we know,

{i}^{2}  =  - 1

So!

=  {x}^{2}  - 12 \times(  - 1)

=  {x}^{2}  + 12

And thus we get the answer!
