Manufacturers rate batteries in watt-hours; if they rate the watt-hour higher, the longer the battery can be expected to last.

A if they rate the watt-hour higher, the longer
B rating the watt-hour higher, it is that much longer
C the higher the watt-hour rating, the longer
D the higher the watt-hour rating, it is that much longer that
E when the watt-hour rating is higher, the longer it is

Not sure how to post / hide OA ?

C is correct. The idiom tested here is: the more X, the more Y (here more is a generic term that can be replaced with any comparative words)

To post the OA, one generally use spoilers. So, to post OA in spoiler, you need to type someting like OA: C. And then select that part and click on spoiler button. You can even preview the message before submitting to make sure that you've underlined, bolded, or used spoilers for the correct portion..

@rphardu: You can use Spoiler to hide the OA.

A and B can be eliminated right off the bat; manufacturers are not rating the watt-hour itself.

C is parallel and work well: "the higher..., the longer..."

D gets overly wordy and awkward by adding "it is that much", which ruins the parallel form.

E uses "it", which is ambiguous.

Also id it right to assume that 'when' refers to time an event takes places and so its usage in E is incorrect.Please clarify!!

Correct.
E implies that it is expected to last only at a particular moment: WHEN the rating is higher.
Not the intended meaning.

"Target Test Prep is the closest to the official version of the GMAT exam, about 99% accuracy in terms of the quality and quantity of information. The course has excellently created singular sets of focused lessons and tests for every possible topic that one could come across in the official GMAT exam."

"The TTP course maximizes the efficiency of the time you spend studying. It will take time and effort but I could almost guarantee that if you complete the course exactly as it is laid out you will get an amazing score. They also have a very responsive team willing to help with any questions you might have."

"TTP has two things that I think no other test prep company offers: A teaching approach that reinforces understanding and an attitude that will give you the mental preparedness needed to succeed on the test. TTP gives you a deep understanding of the concept you need to know while teaching you how to think."
