Answer:
Coldest
Step-by-step explanation:
The mountains of Wales, Scotland, the Pennines in Northern England, and the moors of South West England have the coldest climate all year around due to the presence at high altitude. In winter season, these mountains have average temperature between 2 to -2 degree Celsius which make their environment very cold. Scotland is considered as the coldest part of the United Kingdom throughout the year, and it has average minimum temperatures of -0.2 degree Celsius during the winter.
