Land covered by seawater flooding is not appropriate for plant growth after the salty flood water has drained away. Which water-potential values in the xylem and in the soil water help to explain why land flooded with salty water is unsuitable for plant growth?
- Axylem: $-1800\,\text{kPa}$, soil water: $-700\,\text{kPa}$
- Bxylem: $-700\,\text{kPa}$, soil water: $-1800\,\text{kPa}$
- Cxylem: $-700\,\text{kPa}$, soil water: $-300\,\text{kPa}$
- Dxylem: $0\,\text{kPa}$, soil water: $-1800\,\text{kPa}$
