Oil spill is a man-made disaster that may cause:

Choosing destruction of the marine ecosystem as the correct answer highlights the significant environmental impact that oil spills have. Oil spills introduce toxic substances into the water, which can severely harm marine life. The oil coats the surface of the water, creating a barrier that affects oxygen exchange and impairs the ability of aquatic organisms to thrive. This contamination can harm fish populations, disrupt food chains, and lead to long-term ecological changes in affected areas. Additionally, oil spills can affect the livelihoods of communities dependent on fishing and tourism, causing economic turmoil.

Other options such as nourishment for the earth, wildfire, and nourishment for fishes do not accurately reflect the consequences of oil spills. These alternatives suggest positive outcomes that are not associated with the devastation caused by oil spills. They overlook the harsh reality of the environmental damage and bioaccumulation of toxins in marine ecosystems that follow such disasters.
