Seismology is the scientific study of earthquakes and the propagation of elastic waves through the Earth. It includes the study of earthquake sources, fault mechanics, seismic wave propagation, and Earth's internal structure. The word derives from the Greek 'seismos' meaning earthquake. Archaeology studies human history through excavation. Astronomy studies celestial objects. Environmental Physics is not a standard named discipline.

Ornithology is the scientific study of birds, including their behavior, physiology, classification, ecology, and conservation. The term derives from the Greek 'ornis' meaning bird. Ariology is not a recognized scientific discipline. Botany studies plants. Geology studies Earth's solid matter and processes.

Genetics is the science of genes, heredity, and the variation of organisms. It studies how traits are passed from parents to offspring through DNA, the molecular structure of genes, mutations, and genetic variation within populations. The term derives from 'genesis' meaning origin or creation. Geology studies Earth's physical structure. Parentology and Hereditory are not legitimate scientific terms.

Linguistics is the scientific study of language, including its structure, grammar, syntax, phonetics, semantics, and the psychological and social aspects of language use. It encompasses theoretical, descriptive, and applied linguistics. Verbology is not a recognized discipline. Vocabulary refers to word stock but is not a science. Entomology studies insects. Linguistics provides the systematic study of all aspects of human language.

Oceanography is the scientific study of Earth's oceans, including their physical and biological aspects, mapping, and ocean currents. The term combines 'ocean' (sea) and 'graphy' (study of). Aerodynamics deals with air movement, Environmental Study is broader, and 'Marinology' is not a standard scientific term.

Horticulture is the science and art of growing fruits, vegetables, flowers, and ornamental plants. It focuses on garden cultivation and plant propagation. Agriculture is broader (crops+livestock), Pisciculture is fish farming, and Botany is plant science overall.

Cytology is the study of cells - their structure, function, and pathology. The prefix 'cyto-' means cell. Microbiology studies microorganisms (including cells), Molecular Science covers molecular interactions, and Astrophysics deals with celestial bodies.

NASA's Chandra X-ray Observatory is named after Subrahmanyan Chandrasekhar, the Indian-American physicist who won the 1983 Nobel Prize in Physics for his work on stellar evolution and the Chandrasekhar limit. C.V. Raman was also a Nobel laureate (1930, Physics) but NASA does not have a major telescope named after him. Meghnath Saha and Vikram Sarabhai were distinguished Indian scientists but not the namesake of any NASA satellite telescope.

Rolling Stone magazine is primarily known for its music coverage, including interviews, album reviews, and music industry news. While it covers politics and pop culture, music journalism remains its core identity and biggest draw.

Sunlight travels at approximately 299,792 km/s and takes about 8 minutes 20 seconds to cover the 150 million km distance from the Sun to Earth. Option B is the closest to this scientific fact.
