Final answer:
For HMDA data reporting, all selected ethnicity and race categories by an applicant must be reported, ensuring compliance with discrimination prevention laws.
Step-by-step explanation:
When an applicant selects one or more ethnicity categories and subcategories for HMDA (Home Mortgage Disclosure Act) data reporting, the answer is A) All selected. This means that if an applicant chooses to provide this information, they must report all ethnicity and race categories that they have identified with, not just a subset of them. This requirement is to ensure that lenders comply with equal credit opportunity, fair housing, and home mortgage disclosure laws, aiming to prevent discrimination and promote fairness in the lending process
