Electrical conductivity of medium salinity is -

Correct option is C

· Salinity Classification:
· Electrical conductivity (EC) is a measure of soil salinity, expressed in deciSiemens per meter (dS/m).
· Medium salinity corresponds to 0.75 to 2.25 dS/m.
· Other Ranges:
· Low salinity: Less than 0.25 dS/m.
· High salinity: More than 2.25 dS/m.
