Concept:
The seals of the Indus Valley Civilization are among the most important archaeological discoveries of ancient India. These seals were used for:
• Trade identification
• Administrative control
• Religious symbolism
• Ownership marking
Most Harappan seals were made from:
\[
Steatite
\]
Step 1:
Steatite is a soft stone that:
• Allows fine carving
• Can be polished
• Becomes harder after firing
Because of these properties, Harappan artisans widely used steatite for seal making.
Therefore:
\[
Assertion (A) is correct
\]
Step 2:
Terracotta objects were common in the Indus civilization, but terracotta:
• Is comparatively fragile
• Can chip or crack easily
• Is less durable for repeated stamping
Seals needed:
• Durability
• Fine carving precision
• Long-term usability
Thus, terracotta was generally unsuitable compared to steatite.
Therefore:
\[
Reason (R) is correct
\]
Step 3:
The Reason properly explains the Assertion because:
• Steatite was preferred precisely because stronger and more durable material was needed than fragile terracotta.
Hence:
\[
Reason correctly explains Assertion
\]
Step 4:
Harappan seals are historically important because they:
• Preserve the undeciphered script
• Show artistic sophistication
• Reflect trade systems
• Indicate religious symbolism
Step 5:
Since both statements are correct and the Reason explains the Assertion, the correct answer is:
\[
\boxed{\text{(1) Both (A) and (R) are correct and (R) is the correct explanation of (A)}}
\]
