What field of study does cosmology focus on?

• A. The study of planetary systems
• B. The study of star formations
• C. The properties, structure, and evolution of the universe
• D. The study of black holes

Answer: (C)

Cosmology is fundamentally concerned with understanding the universe as a whole, which includes examining its properties, structure, and evolution from the Big Bang to its current state and future possibilities. This field investigates the large-scale structures of the universe, the cosmic microwave background radiation, the distribution of galaxies, dark matter, and dark energy, as well as the overall dynamics of cosmic expansion. While the other choices focus on specific celestial entities or phenomena—like planetary systems, star formations, or black holes—they do not encompass the broader, more comprehensive inquiry that defines cosmology. Hence, the correct answer accurately captures the essence of cosmology's focus on the universe itself rather than on individual components within it.
