   Auto accidents often involve falling or being bumped on

   The conclusion doesn't care where our fall or head-bump came from, so it's pretty immaterial what frequency of them result from auto accidents. The fact that an auto accident might have led to our fall or head-bump doesn't give us any way to argue that "See? In this case, we needn't get a complete course of treatment from LIC."

   Nonautomobile accidents other than those involving falls or bumps on the head also occasionally

   This has the same feel as (B). Some falls and head-bumps come from auto accidents; some come from non-auto accidents. So what? The conclusion doesn't care where the falls or head-bumps came from, so the frequency with which they come from cars or not-cars has no impact.

   It is very uncommon for falling or being bumped on the head to result in a sudden sharp

   Why this is right

   This weakens the argument by giving us a storyline in which "we have a fall or head-bump", but "we do not need to insist on a complete course of whiplash treatment". After all, if most falls or head-bumps don't result in a sudden sharp motion of the neck, then they don't result in "whiplash", so there'd be no reason to get a complete course of whiplash treatment. This correct answer is easier to like if you see the buried conditional trigger in the conclusion (any) and think of how strong and universal that makes the conclusion: every single time you have a fall or a bump on the head, you should get a complete course of whiplash treatment?

   The appropriate treatment for whiplash caused by a fall or a bump on the head is no different from that for whiplash

   If anything, this lack of distinction would help the author's conclusion (which is not distinguishing between different types of falls or bumps on the head). If the appropriate treatments for different types of whiplash were different, that could potentially be an objection to the conclusion, which is making a blanket recommendation for all injuries of a certain type.
