Which definition of 'area' corresponds to a subject or field of study?

• A. A geographical region
• B. A subject or field of study
• C. Part of a surface or space
• D. An area of land

Answer: (B)

Area has more than one meaning, and in academic contexts it can refer to a field or branch of knowledge. When we talk about “an area of study,” we’re naming a domain of learning, not a physical space. That’s why this option is the best fit: it captures the sense of a subject or field you might specialize in or research. The other senses refer to tangible places or surfaces—like a geographic region, a portion of a surface, or land—and aren’t about knowledge domains. For example, researchers might say they work in the area of cognitive psychology, which clearly uses area to mean a field of study.
