Sublimation is the transition of a substance directly from the solid to the gas phase. So, the answer should be B.

it refers to race, i am pretty sure this was a popular term in nazi germany or something.

its main object was the establishment of "settlement houses" in poor urban areas, in which volunteer middle-class "settlement workers" would live, hoping to share knowledge and culture with, and alleviate the poverty of, their low-income neighbors.
