Hi abhasjha,

The language in the answer choices (usage of the words "as" and "than") implies a comparison, so we have to compare "like" things and do so in proper Parallel format.

On Test Day, GMAT SCs will use a variety of "2-part" phrases. Some of them are common ("either...or", "neither...nor") while some are rarer ("just as...so"). Here, the rarer 2-part phrase "no less....than" appears in the answers. If that phrase correctly compares two things in Parallel format, then that's the correct answer. We have "the development of the compact disc" and "the use of the new technology..."; these phrases ARE parallel and the rest of the answer causes no grammatical problems, so this is the correct answer.

Final Answer: C

GMAT assassins aren't born, they're made,

What was as remarkable as the development of the Compact Disc has been the use of the new technology to revitalize, in better sound than was ever before possible, some of the classic recorded performances of the pre-LP era.

A) What was as remarkable as the development of the Compact Disc
B) The thing that was as remarkable as the developing the Compact Disc
C) No less remarkable than the development of the Compact Disc
D) Developing the Compact Disc has been none the less remarkable as the development than
E) Development of the Compact Disc has been no less remarkable as

STAY IN ONE TENSE unless a change in tense is required.
A: What was remarkable...has been the use
B: The thing that was remarkable...has been the use
Here, the mix of the past tense (was) and the present perfect (has been) conveys an illogical sequence.
Eliminate A and B.

In D, developing and development are redundant.
Eliminate D.

In E, less...as is unidiomatic.
The correct idiom is less THAN.
Eliminate E.

The correct answer is C.
