In semi-arid regions P/PET ratio stands between -

Correct option is C

· Correct answer: (c) 0.20 to 0.50
· In semi-arid regions, the P/PET ratio (Precipitation/Potential Evapotranspiration) typically stands between 0.20 and 0.50. This indicates that the region experiences moderate rainfall relative to potential evaporation.
Other options:
· (a) 0.50 to 0.75: This ratio is more typical of regions with slightly higher rainfall.
· (b) 0.03 to 0.20: This would indicate very dry regions.
· (d) 0.75 to 1.00: More typical of humid regions rather than semi-arid.
