Answer:
The best soil for gardening is option 2
Step-by-step explanation:
Loamy soil is the ideal soil for gardening because it is the best for adequate plant growth. A good combination of sand, silt and clay gives the best kind of soil for plant growth. This allows for adequate pores in the soil which is very important for the plant roots and for the passage of water and air into the roots of the plants. The ideal combination for a loamy soil in terms of sand, clay and silt is 40%, 20% and 40% respectively. The best option is the second option which is closest to the ideal loamy soil composition.
