These terms represent fundamental concepts in astrophysics and particle physics—specifically black holes (Event Horizon, Singularity) and the nature of matter and forces (String Theory, Standard Model)—which are essential for observing and understanding the Universe. Option (c) is incorrect because these terms describe theoretical frameworks and cosmic phenomena rather than the practical engineering and mechanics involved in satellite deployment. The core concept being tested is the candidate's familiarity with contemporary scientific terminology related to cosmology and fundamental physics.
