The study of the universe's origin, structure, and evolutionAnswer & explanation
Answer: C) Cosmology
Meaning: cosmology = the study of the universe as a whole — its origin, its structure and its evolution *(ब्रह्मांड विज्ञान)*.
Greek kosmos = the ordered universe, -logy = the study of.
The Big Bang, the expansion of space and the ultimate fate of the universe are all cosmology's questions, and the stem names exactly those three concerns.
Why the others are wrong.
• Astronomy = the study of celestial objects such as stars, planets and galaxies *(खगोल विज्ञान)* — it observes the contents of the universe, not the history of the universe itself.
• Astrophysics = the branch of physics that explains how celestial bodies work *(खगोल भौतिकी)* — it asks how a star burns, not how the cosmos began.
