想請教一下這一篇的最後一句話，有點看不懂:
Conversely, most small asteroids should be monolithic, because impact fragments easily escape their feeble gravity.
這邊我的理解: 因為受到撞擊的部分都會很容易逃離引力，所以相反的，小的行星都是一整塊的
==>請問這樣不是表示，小行星之所以是一整塊的，就是因為被撞擊後很容易逃脫引力?
以此理解推論的話，下面這題的d選項哪裡錯了呢? 謝謝
The passage implies which of the following about the five asteroids mentioned in line 12?
(A) Their rotation rates are approximately the same.
(B) They have undergone approximately the same number of collisions.
(C) They are monoliths.
(D) They are composed of fragments that have escaped the gravity of larger asteroids.
(E) They were detected only recently.
