B. Decreases

C. Varies

D. No such relation exists

Answer: Option A

Solution(By Examveda Team)

With increasing water content, the Thermal conductivity of soil Increases.
As per the studies, it is seen that soil thermal conductivity increases as a power function of soil moisture content. The thermal diffusivity first increases with increasing soil moisture, then decreases after reaching its maximum.
