When asteroids collide, some collisions cause an asteroid to spin faster; others slow it down. If asteroids are all monoliths—single rocks—undergoing random collisions, a graph of their rotation rates should show a bell-shaped distribution with statistical “tails” of very fast and very slow rotators. If asteroids are rubble piles, however, the tail representing the very fast rotators would be missing, because any loose aggregate spinning faster than once every few hours (depending on the asteroid’s bulk density) would fly apart. Researchers have discovered that all but five observed asteroids obey a strict limit on rate of rotation. The exceptions are all smaller than 200 meters in diameter, with an abrupt cutoff for asteroids larger than that.
The evident conclusion—that asteroids larger than 200 meters across are multicomponent structures or rubble piles—agrees with recent computer modeling of collisions, which also finds a transition at that diameter. A collision can blast a large asteroid to bits, but after the collision those bits will usually move slower than their mutual escape velocity. Over several hours, gravity will reassemble all but the fastest pieces into a rubble pile. Because collisions among asteroids are relatively frequent, most large bodies have already suffered this fate. Conversely, most small asteroids should be monolithic, because impact fragments easily escape their feeble gravity.

The conclusion mentioned in line 16 is that "asteroids larger than 200 meters across are multicomponent structures or rubble piles." We are also told that rubble piles would fly apart if they spin faster than once every few hours. Any asteroid spinning faster than once every few hours must not be a rubble pile.
Choice (D) is an example of an asteroid larger than 200 meters that DOES spin faster than once every few hours. That asteroid must not be a rubble pile, going against the conclusion in line 16.
Quote:
If the bits moved FASTER than their mutual escape velocity, then the bits would "escape" from each other and the large asteroid would remain blown to bits. However, if the bits move SLOWER than their mutual escape velocity, the bits will not escape from each other and, instead, will reassemble due to gravity. Thus, after being blown to bits, most of the bits of the large asteroid will reassemble, explaining the tendency for large asteroids to persist after collisions. (E) is the correct choice.

So the conclusion is---Asteroids>200m would spin slowly..
Option D says just the opposite.

Passage breakdown
In the first paragraph (P1), the author introduces a hypothesis and provides supporting evidence:
- Background: the rotation rates of asteroids depend on whether those asteroids are monoliths or loose rubble piles.
- Hypothesis: monoliths should show a bell-shaped distribution with some fast rotators, while rubble piles should not have any fast rotators
- Supporting evidence: large asteroids are all slower, whereas a few small asteroids are faster.
In the second paragraph, the author draws a conclusion from the info in P1, then supports this conclusion:
- Conclusion: large asteroids are rubble piles.
- Support for this conclusion: computer modeling data.
- Addition to conclusion: small asteroids are monoliths.
