Answer: Northwestern Europe
Explanation: Such a climate with mild and rainy winters and cool, humid summers is characteristic of most of northwestern Europe, such as in Britain. The reason for this is the relative proximity of the oceans to most of northwestern Europe, from where warm winds also known as breezes, come ashore and does not make the winter cold, that is, make them mild and rainy. On the other hand, in the summer, a slightly cooler wind blows from the ocean, carrying moisture. Such a climate is known as the Marine West Coast Climate.
