If the sun were to disappear from the universe tomorrow, it would affect all spheres.
The atmosphere would be impacted as the sun provides the necessary heat and energy that drives weather patterns and maintains the atmosphere's structure. The biosphere, which includes all living organisms on Earth, would be drastically affected since it relies on sunlight for photosynthesis, and without the sun, most life forms would struggle to survive. Other spheres like the geosphere and hydrosphere would also be affected as changes in temperature and energy would influence geological processes and water cycles.
Therefore, the correct response is all spheres.
