Why the answer is B, and why the others tempt you.
**The reasoning**
Loamy soil is the **ideal agricultural soil** because it's perfectly balanced. It contains roughly equal parts of sand, silt, and clay. This combination gives you the best of all worlds:
- **Good drainage** (from sand) — so roots don't drown
- **Water retention** (from clay and silt) — so crops don't dry out quickly
- **Rich in nutrients** (organic matter sticks well to it)
- **Easy to work with** — not too heavy, not too loose
- **Good aeration** — roots can breathe
Think of it as the "Goldilocks soil" — not too sandy, not too clayey, just right!
**Why the wrong options tempt you**
**Sandy soil** drains *too* fast — water and nutrients wash away before crops can absorb them. It's too loose.
**Clayey soil** holds water *too* well — becomes waterlogged, heavy, and poorly aerated. Roots struggle.
**Stony soil** is obviously poor — rocks don't retain water or nutrients, and they block root growth.
**Quick takeaway**
**Loamy = balanced texture = best crop performance.** Remember: farmers pray for loam because it combines drainage, retention, and fertility perfectly.
