Everybody knows that 'water seeks its own level' but very few people know why water seeks its own level. The reason has most to do with

  1. atmospheric pressure

  2. water pressure depending on depth

  3. water's density

  4. value of 'g'

B Correct answer
Explanation

Water seeks its own level due to water pressure increasing with depth (P = rho * g * h). In connected vessels, water flows until pressures at the same horizontal level equalize, which occurs when water surfaces are at the same height. Atmospheric pressure is the same on all surfaces and cancels out, while density and 'g' don't determine level-seeking behavior.
