The correct answer is option 'C', which is EF.

Explanation:

Plateau Station is located in Antarctica, which is known for its extreme climate conditions. The climate type portrayed by Plateau Station is EF, which stands for Ice Cap Climate. This climate type is characterized by extremely cold temperatures and permanent ice cover.

1. Ice Cap Climate (EF):
- The EF climate type is found in polar regions, such as Antarctica, where the average temperature of the warmest month is below 0°C (32°F).
- The temperatures at Plateau Station are consistently below freezing throughout the year, with average temperatures ranging from -20°C (-4°F) to -60°C (-76°F).
- The EF climate is also characterized by high winds, low humidity, and little precipitation. These conditions contribute to the preservation of ice and the formation of ice caps.

2. Other Climate Types:
a) Dw - Desert Climate:
- Desert climate is characterized by arid conditions, with very little precipitation and high temperatures.
- It does not match the climate type of Plateau Station, as Antarctica is not known for its high temperatures or arid conditions.

b) ET - Tundra Climate:
- Tundra climate is characterized by low temperatures and a short growing season.
- While Plateau Station does experience low temperatures, it does not have a significant vegetation cover or a short growing season.

c) Df - Humid Continental Climate:
- Humid continental climate is characterized by distinct seasons, with cold winters and warm summers.
- Plateau Station does not experience warm summers or distinct seasons, as it is located in the polar region.

In conclusion, Plateau Station in Antarctica portrays the EF (Ice Cap Climate) type of climate, which is characterized by extremely cold temperatures, permanent ice cover, high winds, low humidity, and little precipitation.
