**Question:**Which of the following observatories is most likely to discover a black hole in a binary system?- **A. the Chandra X-Ray Observatory**- **B. the SOFIA airborne infrared observatory**- **C. the Arecibo Radio Observatory**- **D. the Hubble Space Telescope****Answer Explanation:**The Chandra X-Ray Observatory (Option A) is most likely to discover a black hole in a binary system because it specializes in detecting X-rays emitted by matter in accretion disks around black holes. **Detail:**- **Chandra X-Ray Observatory:** Specifically designed for detecting X-rays from high-energy regions, which is ideal for observing black holes.- **SOFIA Airborne Infrared Observatory:** Focuses on infrared light, useful for studying cooler cosmic objects.- **Arecibo Radio Observatory:** Historically used for radio waves, not operational since 2020.- **Hubble Space Telescope:** Excellent for visible and ultraviolet light but not specifically optimized for black holes.
