The soil moisture tension at the permanent wilting point is usually around 15 atmospheres or -15 bars. This is the point at which plants can no longer extract enough water to meet their needs and remain wilted until water is added to the soil.

Moisture Tension at Permanent Wilting Point
Moisture tension is the attractive force that water molecules have to the soil particles. It is the force that opposes the movement of water out of the soil. The moisture tension at permanent wilting point is the threshold tension below which plants cannot extract water from the soil, leading to permanent wilting.
Commonly Adopted Moisture Tension
The commonly adopted moisture tension at permanent wilting point is 15 atmospheres. This means that at a tension of 15 atmospheres, the soil water potential is so low that plants cannot extract water from the soil, leading to permanent wilting.
Other Options
Option B (7 atmospheres) is too low for the moisture tension at permanent wilting point. Plants can still extract water from the soil at a tension of 7 atmospheres, so it is not the threshold tension for permanent wilting.
Option C (45 atmospheres) and option D (150 atmospheres) are too high for the moisture tension at permanent wilting point. The soil water potential at these tensions is too low for any plant to extract water from the soil, not just at the permanent wilting point.
Therefore, the correct answer is option A (15 atmospheres) as it is the commonly adopted moisture tension for the permanent wilting point.
