From B.  ..."check stubs, written letter from an employer, W-2 forms, etc., in order to..."

The term "etc." is not appropriate for the Virginia's Administrative Code.   Something more formal like:

"...shall include, but not limited to check stubs, written letter from an employer, and W-2 forms, in order to..."

Also - there is no mention of Virginia or Federal Income Tax Returns.  I suggest adding both of the these to list.

From C.  "Proof of income must include:..."   How is someone of a fixed income - such as disability, social security, or retirement income going to provide proof of income from an employer?
