Answer: (D) Astronomy
Astronomy is a natural science that involves the scientific study of celestial objects (such as stars, planets, comets, galaxies, and nebulae), the universe as a whole, and the phenomena that originate beyond Earth's atmosphere. It uses principles of mathematics, physics, and chemistry to understand their origin, evolution, physical and chemical properties, and behavior. While cosmology is a branch of astronomy that focuses on the universe's origin, evolution, and large-scale structure, astronomy encompasses the broader study of all extraterrestrial objects and phenomena.
