The paralleism structure is like " noun foloowed by a prep. phrase"

fluctuations(noun) in local seismic activity(prep. phrase)

D follows the same suit

D for ||ism.

Also to seperate E from D. Just look at the "in" word in D. it is used after changes: "changes in" and "variations in". This is parallel and E is not.

Also I'm not sure about Idiom use of variations. varitions in always correct?

Anyone?

Tilting is used as a noun

so A, B and C are out

Between D and E Its D because E appears to change the meaning

Changes in the measurements of strains across a zone. Sort of saying like the measurement of weight was in Kgs, now its in lbs.

D keeps it intact.
