(a) The county is without sufficient funds in its treasury to make the payment.
(b) The county is unable to provide such funds, by temporary borrowing or otherwise.
(c) Registered warrants of the county are not readily salable or exchangeable in the community by holders for their face value in cash.
(d) The county has made provision in its current budget for the expenditures for the aids for which it is liable under the Welfare and Institutions Code and has levied the necessary taxes.
