The correct answer is:
(a) A-B-C-E
Explanation:
In the Köppen climate classification system, the following climate types represent humid conditions:
- A: Tropical (Rainforest and Monsoon climates) — These climates are warm and have high humidity with significant rainfall throughout the year.
- B: Arid (Desert and Semi-arid) — These are dry climates, not humid, so they do not meet the condition for humid climates.
- C: Mild/Temperate (Humid Subtropical, Mediterranean) — These climates have mild winters and moderate humidity.
- E: Polar (Tundra and Ice Cap) — These are cold climates that may have some moisture but are generally not considered humid.
Thus, A-B-C-E are more closely related to humid conditions, with B being the outlier that is not typically humid but still fits the broader context of climates.
