Which of the following statement is NOT true in the context

Which of the following statement is NOT true in the context of capillary pressure in soils?

1. Water is under tension in capillary zone
2. Pore water pressure is negative in capillary zone
3. Effective stress increases due to capillary pressure
4. Capillary pressure is more in coarse grained soils

Void ratio and size of voids is more for coarse grained soil than fine grained soil. So coarse-grained soil will have less capillary pressure.
