The correct answer is A. Cwg.
Köppen’s climate classification is a system that classifies climate into five main climate groups, with each group being divided into several subtypes. The five main climate groups are:
- A: Tropical climates
- B: Dry climates
- C: Temperate climates
- D: Continental climates
- E: Polar climates
The subtypes of
each climate group are based on the average temperature and precipitation of the region.The climate of North Bihar is classified as Cwg because it has a warm, humid subtropical climate with hot,
humid summers and mild, dry winters. The average temperature in North Bihar ranges from 20°C (68°F) in January to 35°C (95°F) in May. The average annual precipitation is 1,200 mm (47 in).The other options are incorrect because they do not accurately describe the climate of North Bihar. Option B, Aw, is a tropical savanna climate with a hot, dry season and a warm, wet season. Option C, Caw, is a Mediterranean climate with warm, dry summers and cool, wet winters. Option D, CBW, is a continental climate with hot, dry summers and cold, snowy winters.
