B. Place the light bulb behind the observer.

Step-by-step explanation:

If you are going for a solar eclipse, then the experiment would work since it's the sun, the moon, the earth. But since you are looking to see a lunar eclipse, you must make the order be the sun, the earth, the moon. For this, her back has to be toward the light.
