Which term is synonymous with "desolate"?

The term "forlorn" is synonymous with "desolate" because both words convey a sense of abandonment and loneliness. When something is described as desolate, it often highlights a state of emptiness, isolation, or a bleak and barren condition. Similarly, "forlorn" evokes feelings of being abandoned, pitifully sad, or in a state of hopelessness. This shared connotation of sadness and emptiness makes "forlorn" an appropriate synonym for "desolate."

The other terms do not convey the same sense of emptiness or abandonment. "Abundant" and "flourishing" suggest richness and growth, while "populated" indicates a large number of people or things in a given area. None of these options capture the essence of desolation as effectively as "forlorn" does.
