The correct answer is Desert climate.

In the Koeppen climate classification system, ‘B’ denotes arid (dry) climates. The second letter ‘W’ stands for ‘Wüste’ (German for desert), indicating an extremely arid climate. ‘S’ stands for ‘Steppe’, indicating a semi-arid climate.

The first letter in the Koeppen system classifies the main climate type (A – Tropical, B – Arid, C – Temperate, D – Continental, E – Polar). The second letter, for B climates, differentiates between desert (W) and steppe (S). Subsequent letters provide more detail about temperature or precipitation patterns.
