Answer to Question 1

B

Answer to Question 2

Just as the S asteroids are most common, so stony meteorites are also abundant. But they blend in with similar surface rocks on Earth, and weather quickly as well. Iron meteorites are very durable, and much denser and often magnetic, which makes finding them easier in most cases.
