Why the answer is B, and why the others tempt you.
**The reasoning**
Loamy soil is the **agricultural champion** because it's a balanced mixture of sand, silt, and clay (roughly 40-40-20). This perfect blend gives it:
- **Good drainage** (from sand) — so roots don't drown
- **Nutrient retention** (from clay and silt) — holds fertilizers and minerals plants need
- **Easy root penetration** (not too compact, not too loose)
- **Water retention** (holds moisture but doesn't waterlog)
This balance creates the ideal environment for most crops — yam, maize, cassava, vegetables — making it the gold standard for farming.
**Why the wrong options tempt you**
**Building/Road making** — You might think "loam sounds strong," but builders need **clay soil** (compact, stable when dry) or laterite.
**Pottery** — This needs **pure clay** that's moldable and hardens when fired. Loam has too much sand mixed in.
The trap: confusing soil *structure* with soil *purpose*.
**Quick takeaway**
**"Loam = Balanced = Best for crops."** When you see "loamy soil," think "farmer's choice" — it's agriculture's sweet spot.
