What Usually Occurs in a "Reciprocal Lending

What usually occurs in a "reciprocal lending"?

A) A deposit is made under the condition that the person making the deposit receives a loan in return, which will be defaulted. The S&L fails, and the taxpayers bail everyone out.
B) A "straw borrower" receives a kickback for having the loan in his or her name, and someone else pockets the money and defaults on the loan.
C) Land is sold by the original owner at market value, and a fraudulent appraisal results in the land being resold for twice the market value, which results in profits for all involved.
D) Executives from different S&Ls make loans to each other.
