Step-by-step explanation:
The answer is dutch........
I'd say the mode is probably also 12.
we will proceed to solve each case to determine the solution of the problem
we know that

<u>case A</u>. 

<u>The result of case A is not a real number product</u>
<u>case B</u>. 

<u>The result of case B is not a real number product</u>
<u>case C</u>. 

<u>The result of case C is not a real number product</u>
<u>case D</u>. 

<u>The result of case D is a real number product</u>
therefore
<u>the answer is the option</u>
