Final answer:
A consumer protection bureau handles complaints regarding mortgage loan rejections.
Step-by-step explanation:
The correct answer is C) A consumer protection bureau. When it comes to handling complaints regarding mortgage loan rejections, a consumer protection bureau is typically responsible.
In the United States, one such consumer protection bureau is the Consumer Financial Protection Bureau (CFPB). This agency was created in 2011 to oversee the financial industry and protect consumers from abusive practices, including sub-prime mortgage lenders.
It is important to note that lenders and real estate agents may be involved in the mortgage loan application and approval process, but they do not handle complaints regarding loan rejections.
