Yes, it is not guaranteed to happen.

However, B is most supported. A,C,D, and E are simply incorrect. B is totally reasonable, plausible, and supported (unlike the other 4 answers). Just not guaranteed.

There is no advantage to simply "having a score" unless you have reason to believe that you're going to apply soon. If you're not ready, chances are you will not be applying soon unless you intend to go to a school that casts a very wide net regarding LSAT scores.
