Answer:
According to NASA, we can expect:
A) Frequent power grid disturbances: Sunspots are areas on the surface of the sun that have intense magnetic activity. This magnetic activity can cause disruptions in the Earth's magnetic field. When this happens, it can induce electric currents in power transmission lines, leading to power grid disturbances. These disturbances can result in blackouts or fluctuations in the power supply.
B) Ozone depletion in the upper atmosphere: Solar flares and coronal mass ejections (CMEs) are often associated with sunspots. These events release a large amount of energy, including intense ultraviolet (UV) radiation. This high-energy radiation can interact with molecules in the Earth's upper atmosphere, such as ozone (O3), causing it to break down. This leads to ozone depletion, which can have consequences for the Earth's climate and the health of living organisms.
C) Increased radio and satellite communications systems disturbances: Sunspots can generate powerful bursts of electromagnetic radiation, including radio waves. These bursts can interfere with radio and satellite communications systems on Earth. The disturbances caused by sunspot activity can disrupt communication signals, leading to degraded or interrupted communication services for various applications like television, radio, GPS, and satellite-based internet.
