The correct answer is:
c. clay and humus, but poor in sand ❤️
Here’s why:
1. Role of soil components in water retention
Clay:
Very small particles → large surface area → holds water tightly.
Helps retain water but may reduce drainage.
Humus (organic matter):
Improves soil structure.
Increases water-holding capacity and nutrient retention.
Sand:
Large particles → water drains quickly → poor water retention.
