WHY DON'T ALL FISH DIE WHEN LIGHTNING HITS THE SEA?

  1. water is a good conductor of electricity,so it passes the eletricity to the ground level

  2. All fish stay deep inside the sea so electricity cannot reach there

  3. The amount of salt in sea help electricity to reduce its power to lower level

  4. lightning hits the sea and spreads out straight away and becomes harmless to all

D Correct answer
Explanation

When lightning strikes the sea, the electricity spreads out rapidly across the water surface and dissipates. Since water is a conductor, the charge disperses over a large area, reducing the current density to levels that aren't lethal to most fish. Fish deep underwater are further protected as the current primarily affects the surface.
