The number of uninsured won’t fall as much as expected

"Generous subsidies will be available for sick people and families with children who really need medical care to buy individual coverage, but healthy single people between the ages of twenty-six and forty, say, will still have a financial incentive to remain outside the system until they get ill, at which point they can sign up for coverage. Consequently, the number of uninsured won’t fall as much as expected, and neither will prices." (https://www.newyorker.com/news/john-cassidy/obamacare-by-the-numbers-part-2/amp)

Consider the following sentence, please:

1) Consequently, the number of uninsured won’t fall as much as expected, and neither will prices.

Can I write the underlined as-clause like this also:

a) ...won’t fall as much as it is/was expected to fall. (Here the as-clause is: Sub+Aux V+Main V+to-infinitive)

b) ...won’t fall as much as it is/was expected. (Here the reduced as-clause is: Sub+Aux V+Main V)

c) ...won’t fall as much as is/was expected. (Here the more reduced as-clause is: Aux V+Main V)

Note 1: the as-clause of sentence (1) is even more reduced: Main V.

Note 2: In linguistic terms, the omission of words from a phrase/clause/sentence is called "Ellipsis".
