Option A (race=1 or race=2) would work and select both whites and blacks. Option B (race<3) would work and select whites, blacks, and others. Option D (race<=2) would work and select whites and blacks. 
Option C (race=1 and race=2) would not work because a case cannot be both white and black at the same time, so this command would not select any cases.
