Mr. Miller bought a parcel of land and built a 20-unit apartment building on it. He borrowed 80% of the construction cost using a trust deed to obtain a conventional loan from a state chartered savings and loan association. The building has been completed and Miller is getting ready to lease the units. He has created an application form for new tenants. One of the questions concerns race, since Miller wants to rent only to Caucasians. Under these circumstances, which of the following is correct:

A) Miller's policy is illegal and violates fair housing laws
B) Miller's policy is legal since he owns the property
C) Miller's policy is legal as long as he does not discriminate based on other protected classes
D) Miller's policy is legal as long as he does not advertise it
