Which model states that Earth is at the center of the universe?

• A. Ptolemaic Model
• B. Copernican Model
• C. Geocentric Theory
• D. Heliocentric Theory

Answer: (C)

The idea being tested is whether celestial motion is centered on Earth or on the Sun. A geocentric view places Earth at the center of the universe, with the Sun, Moon, planets, and stars orbiting around it. Among the terms, the Geocentric Theory is the direct label for that Earth-centered perspective. The Copernican Model and the Heliocentric Theory describe a Sun-centered system, so they don’t fit. The Ptolemaic Model is also Earth-centered, but it’s a specific geocentric framework; the question points to the general term that states Earth-centered, which is Geocentric Theory.
