The Reason That Very Few Impact Craters Are Seen on Venus

The reason that very few impact craters are seen on Venus compared with the Moon is believed to be that

A) Venus formed closer to the Sun than the Moon did, where the cratering rate was much lower.
B) due to rainfall and wind, all but the most recent craters have eroded away.
C) lava flows and surface melting have covered all but the most recent craters.
D) the surface of Venus has been subducted down into the planet several times in its history, thereby removing evidence of impacts.
