Correct Answer:
B. No
The Indus Valley Civilization script has not been deciphered. Despite numerous attempts by scholars worldwide, the script remains one of the greatest mysteries of ancient history. There is no widely accepted interpretation of its symbols, meaning that much about the civilization's language, religion, and governance is still unknown. Therefore, stating it has been 'Yes' or 'Partially' deciphered is incorrect. The 'Rosetta Stone' was instrumental for deciphering Egyptian hieroglyphs, not the Indus script.
