Final answer:
To find the values of a and m that make the equation true, set the real and imaginary parts of the equation separately. The correct answer is not provided in the options given.
Step-by-step explanation:
To find the values of a and m that make the equation true, we can equate the real and imaginary parts of the equation separately. For the real part, we have: 6 - a = -12. Solving for a, we find that a = 6. For the imaginary part, we have: 3m = 27. Solving for m, we find that m = 9. Therefore, the correct answer is not provided in the options given.
