Confusion or two right choices

CFA Level I Fixed Income
#1

Hi all,

Here is the question from end of the chapter practice questions regarding Fixed Income:

Securitization benefits financial markets by:

  1. increasing the role of intermediaries.
  2. establishing a barrier between investors and originating borrowers.
  3. allowing investors to tailor credit risk and interest rate risk exposures to meet their individual needs.

The right answer is C (which makes sense); however, to my mind, A also is a right choice based on the chapter about the benefits of securitization. Or, can anyone, pls explain, why A cannot be the right answer?

Thanks

How does having more pervasive middlemen (or middlewomen) benefit financial markets?
