Sentence Correction

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

IMO A ...

whose modifies clans

Can anyone please give an explanation for all the options.

OK, let's try to get the best fit.

I think it is A.

E: first mistake - less limitations, it must be fewer limitations as "limitation" is countable.
D: same here.
C: "where" must refer to a some place. Clan can't be a place, right? so C - out.
B: where... plus, "where there" is wordy and ambiguous.
A: "clans whose access to water" is idiomatical and fine. and "access was less limited (than that of Anasazi prior home's access to water) is clear and right.
So the answer is A. Hope it helped.

thanks man.....makes a lot more sense now....
