Assertion: Human geography attempts to explain the relationship between all elements of human life and the space they occur over.
Reasoning: Human geography is highly inter-disciplinary nature.

Both Assertion (A) and reasoning (R) are correct and R is the correct explanation of A.

The answer is:  Option 1: Both Assertion (A) and reasoning (R) are correct and R is the correct explanation of A.

Here's why:

Assertion (A) is true- Human geography  studies the interactions between humans and their environment, including how social, cultural, political, and economic factors influence the way people live in different places. It essentially examines how all elements of human life are shaped by and interact with geographical spaces.

Reasoning (R) is true and explains A: The interdisciplinary nature of human geography is crucial because it allows for a holistic understanding of these interactions. Human geography draws upon concepts and methods from various disciplines like sociology, economics, anthropology, history, and environmental science to analyze the complexities of human-environment relationships across different spatial scales. This interdisciplinary approach is what enables human geography to effectively explain the connections between human life and the spaces it occupies.

Therefore, both Assertion (A) and Reasoning (R) are true, and R accurately explains why human geography takes an interdisciplinary approach.
