Source GMAT Sets -22

The Acoma and Hopi are probably the two oldest surviving Pueblo communities, both dating back at least a thousand years.
A. both dating
B. both of which have dated
C. and each has dated
D. and each one dating
E. each one of which date

A

I am unable to understand why C is incorrect. The sentence has two independent clauses coordinated using "And"...There is no SV error. Is conciseness the only reason to eliminate C.

Thanks
