Continental climate zone has the greatest change in summer between winter and summer months.
Answer: Option A
Step-by-step explanation:
Continental climate varies to a large extent, annually in terms of temperature. The winds blow overland, and the temperatures do not get normalized by the water bodies such as seas, oceans etc at regions where the continental climate is prevalent.
Summers in such a climate can lead to harsh weather conditions like frequent hot temperatures and thunderstorms. Summers tend to be hotter and winters tend to be very cold in a continental climate, with rainfall being meagre during this climatic condition.
