Step 1: Analyze the assertion.
Assertion A: "Each formal region has distinct boundaries which make them easy to identify." This is correct. Formal regions are typically defined by clear boundaries, such as political or administrative boundaries, that make them easy to identify.
Step 2: Analyze the reasoning.
Reasoning R: "Region is bounded by economic activities." This is also true, as many regions are defined by the type of economic activities taking place within them. However, this does not explain why formal regions have distinct boundaries.
Step 3: Determine the relationship.
- Both A and R are correct, but the reasoning does not directly explain why formal regions are easy to identify. Formal regions are identified based on their political, administrative, or cultural boundaries, not solely by economic activities.
Final Answer:
The correct answer is (D) Both A and R are correct but R is not the correct explanation of A.
