What is the name of the range of hills often referred to as the "Backbone of England"?

The range of hills known as the "Backbone of England" is the Pennines. This name reflects the Pennines' geographical significance, as they stretch roughly north-south through the center of northern England, acting as a natural divide between the west and east of the country. The term "Backbone" symbolizes their prominence in the landscape and their role as a defining feature of England's topography.

The Pennines are characterized by their rugged terrain and scenic beauty, making them a popular area for hiking and outdoor activities. Additionally, they have significant cultural and historical importance, having influenced local wildlife, farming, and settlements over centuries. This central position in the country, along with their height and distinctiveness, justifies the nickname.

In contrast, while the other choices represent notable British landscapes, they do not share the same geographical significance or central role in defining the English landscape as the Pennines do.
