OFFICIAL EXPLANATION
D
First, notice that the sentence contains a list. The state agencies are "using", "consulting", and "studying". "Using" and "studying" can't be changed, so "consulting" (which is parallel with "using" and "studying") must remain the same. That eliminates choices (B) and (E). The three remaining choices differ in the first part of the underlined portion.
Both (A) and (C) use a pronoun, "their" or "them". While it is clear from context that the pronoun refers to the water resources, the GMAT holds you to a higher grammatical standard. In this part of the sentence, there are two plural nouns, "state agencies" and "water resources". Technically, the pronoun could refer to either of those, so "the previous rate" - which could only refer to the rate that water resources are being used - must be correct.

Eliminate B and E. 'Consulting with experts' is the right usage.
I think A and C does not have issues with the pronouns, which have logical antecedents, but D has a better and concise construction.
D is the answer.
