Using the order of operations (PEMDAS), we first perform the multiplication and division from left to right: 
12 - 4 * 3 / 2 + 9 = 12 - 12 / 2 + 9 
Next, we perform the division: 
= 12 - 6 + 9 
Finally, we perform the subtraction and addition from left to right: 
= 6 + 9 
= 15 
Therefore, the answer is B)15.
