  3. Which allows water to pass very quickly from it

  4. Which allows limited amount of water to retain into it

Show answer
Correct Option: B
Explanation:

Water should percolate slowly in a soil because if water passes too rapidly, then many of the minerals and organic matter useful for plants will simply be washed away. If there is no percolation and all the water is simply held up in the soil, then there will be poor aeration and respiration in plant roots will suffer.
