Hey Imskpwr,
This is the issue with hypothetical examples. In this case, getting through the answers is quite easy.
As rainfall began to decrease in the Southwest about the middle of the twelfth century, most of the
Monument Valley Anasazi abandoned their homes to join other clans whose access to water was less
limited.
(A) whose access to water was less limited
(B) where there was access to water that was less limited
(C) where they had less limited water access
(D) with less limitations on water access
(E) having less limitations to water access
(A) Perfect!
(B) "Where" needs to modify a place, but it's modifying "clans". Also, "that was less limited" is modifying "water," which makes no sense./
(C) "Where" needs to modify a place, but it's modifying "clans".
(D) Limitations are countable, so it should be "fewer".
(E) Limitations are countable, so it should be "fewer".
It's generally not a good idea to write your own answer choices and then ask "which one is better," because if something is wrong, it's just wrong. Both of your example answer choices are wrong, so you'd never have to choose between them.
Hope that helps!
