In diagram A, we can see that the light comes from the left, it first impacts on the Earth, and then we have the Moon.
Now, you can model this situation with a flashlight (the Sun) a basketball (the Earth) and a tennis ball (the Moon)
When you point with the flashlight at the basketball, the basketball will look bright, but it will cast a shadow behind it. This shadow will cover the tennis ball, and almost no light will reach the tennis ball, so it will not look bright.
This phenomenon is called a lunar eclipse, and this happens when the Earth is in between the Sun and the Moon. When this happens, we see the moon a bit darker and more reddish.
