Which of the following participates in the primary mortgage market

The Federal Home Loan Bank Board is a regulatory agency, not a lender in the primary mortgage market. Its role is to oversee and regulate the operations of the Federal Home Loan Banks, which support mortgage lending by providing liquidity to the mortgage market but do not engage in originating loans directly to consumers.

Land contract vendors sell property using a method where the buyer makes payments directly to the seller, who retains the deed until the full purchase price is paid. This arrangement does not involve traditional mortgage lending practices; hence, it does not participate in the primary mortgage market where loans are originated by financial institutions.

The World Bank is an international financial institution that provides funding and resources primarily for development projects worldwide. It does not engage in the primary mortgage market, which focuses on personal home loans within local markets, rather than financing large-scale development projects.
