Solution:
Idioms + Parallelism + Pronoun
In A and D, there is pronoun error – “...storm's structure (singular noun)...their (plural)...”
In B, “for gauging the (X and Y) not for the (P and Q)” usage of “for” second time is not idiomatic.
“for the X not the Y” is idiomatic.
In E, “gauging the (X and Y), and not for the (P and Q)”, usage of “and” and “for” is awkward.
In C, “gauging the (X and Y) not the (P and Q)” is parallel as well as idiomatic. Hence, C is the best choice.
In the non underlined part, treatment of “data” as plural due to usage of “are useful” violates subject-verb agreement. “The data collected by weather airplanes that fly into the heart of a hurricane are useful”.
