In which of the following climate groups by Koeppen’s potential evapotranspiration exceeds precipitation?

Correct option is D

Introduction
The Koeppen Climate Classification System defines the major climate groups based on temperature and precipitation characteristics. The defining characteristic of the Dry Climate group (designated by the letter B) is that the rate of potential evapotranspiration (PE)—the amount of water that could be evaporated and transpired—is perpetually greater than the total precipitation received (annual water deficit).
Information Booster
· Koeppen Group: Designated by the capital letter B (for Dry Climate).
· Defining Feature: The essential characteristic of this climate group is the extreme lack of moisture.
· Condition: Potential Evapotranspiration (PE) exceeds Precipitation (P).
· Sub-Groups: It is further subdivided into BW (Arid or True Desert) and BS (Semi-Arid or Steppe).
· Vegetation: Due to the water deficit, vegetation is sparse, consisting mainly of xerophytic plants.
Additional Points
· Warm Temperate Climate, Cold Climate, and Tropical Climate: These climate groups generally receive more precipitation than the rate of potential evapotranspiration, or they have a seasonal water surplus (e.g., tropical wet or warm temperate moist climates).
