Man dreams of emigrating to the moon. If it can be realized, residents on the moon can see () A. Eclipse B. Eclipse C. Eclipse and the moon.

The solar eclipse is due to the arrangement of the sun, the earth and the moon, and the eclipse is formed between the sun and the earth. So if it is on the moon, the eclipse is formed between the moon and the sun. Naturally, this state also exists, and it happens to be the principle of forming an eclipse on the earth (note that the observation object at this time is the sun, and it is certainly possible on the moon). In addition, the solar eclipse on the earth is formed because the earth is between the sun and the moon. It is the earth that blocks the sunlight from reaching the moon (the observed object here is the moon), but on the moon, the observer can't see the moon itself. So there is no eclipse. There will only be one black spot on the earth.

So choose B.
