Step 1: Analyze the assertion.
Assertion A: "In tertiary occupation, there is no derivation from nature." This is correct, as tertiary occupations, such as services, do not directly derive resources from nature (e.g., education, healthcare, finance).
Step 2: Analyze the reasoning.
Reasoning R: "It provides only services so it is known as a service sector." This is also correct, but it does not explain why tertiary occupations do not derive from nature. The explanation focuses on the type of occupation rather than the natural derivation aspect.
Step 3: Determine the relationship.
- Both A and R are correct, but the reasoning does not directly explain the assertion. The explanation focuses more on the nature of tertiary occupations rather than why they do not derive from nature.
Final Answer:
The correct answer is (D) Both A and R are correct but R is not the correct explanation of A.
