Step 1: Concept
The Harappa Civilization, an ancient Indus Valley civilization, produced stone and metal sculptures. The assertion (A) states that very few such sculptures have been found, while the reason (R) claims all discovered sculptures are large in size and made from locally available stone.
Step 2: Meaning
Assertion A indicates a scarcity of surviving Harappan sculptures, suggesting these artifacts were either not produced in great numbers or did not survive well over time. Reason R provides specific details about the characteristics of the few known sculptures: their size and material composition.
Step 3: Analysis
Let's analyze each part:
Assertion A: The statement that very few stone and metal sculptures have been found is supported by archaeological evidence. Harappan sites have yielded a limited number of such artifacts, indicating that these items were perhaps not common or widely distributed.
Reason R: This reason states that all discovered sculptures are large in size and made from locally available stone. While this detail about the size and material might be accurate for some known examples, it does not fully explain why very few sculptures have been found.
The key issue is whether Reason R correctly explains Assertion A. The fact that sculptures were large and made of local materials does not directly address the scarcity of surviving examples. Other factors such as preservation conditions, usage patterns, or production methods could also contribute to this scarcity but are not covered by Reason R.
Step 4: Conclusion
Reason R provides specific details about some discovered sculptures but does not explain why very few have been found overall. Therefore, while both A and R may be correct individually, R is not the correct explanation for A.
Final Answer: (C)
