The correct answer is A, the Real Estate Settlement Procedures Act (RESPA). RESPA and its implementing Regulation X regulate important aspects of settlement services involving federally related mortgage loans.

The Consumer Financial Protection Bureau explains that RESPA applies broadly to federally related mortgage loans and that settlement services include mortgage origination, title services, attorney services, appraisal, recordation, real-estate brokerage services, and other services associated with closing.

RESPA Section 8 specifically prohibits certain kickbacks and referral arrangements involving settlement-service business.

Older practice questions often describe RESPA simply as the statute requiring disclosure of “all closing fees.” That description is too simplistic because modern mortgage disclosures are also governed by TILA and the integrated TRID disclosure regime.

The core exam point is that RESPA addresses settlement practices, disclosures, escrow-related requirements, and anti-kickback rules in qualifying mortgage transactions.
