Final answer:
The correct answer is d) Islands and plains. England is an island nation, being part of the British Isles, and its landscape is largely characterized by rolling plains, especially in the south and east, which are important for agriculture and settlement.
Step-by-step explanation:
The two key geographical features of England are islands and plains. Option (d) is correct. England is part of the British Isles, which are an archipelago (a group of islands) separated from the European mainland by the English Channel. The landscape of England is characterized by rolling plains, especially in the southern and eastern parts, which make up a significant portion of the geography. While England does have some mountainous regions, such as the Pennines running through the north and areas of upland in the south-west, plains are more dominant and crucial to the agricultural landscape.
England's position as an island nation has also been significant throughout its history, influencing its culture, economy, and politics. The English Channel and the North Sea have provided natural defenses as well as opportunities for trade and contact with nearby countries. Thus, the correct geographical features that are key to England are islands and plains.
