Solution:Concept- The main element of the hydrosphere on Earth and the main component of all known living organisms is water. It is a clear, flavourless, odourless, and nearly colourless inorganic compound. Despite the fact that it doesn't provide them with food, energy, or organic micronutrients, all known forms of life are dependent on it.
The Density of water Water has molar mass and Molar volume,
Therefore, the Volume of 1 molecule of water
Hence, the correct answer is option 3.
