Step 1: Understanding the Harappan script.
The Harappan or Indus script is undeciphered but is found on seals, tablets, and pottery. It represents the earliest form of writing in the Indian subcontinent.
Step 2: Number of symbols.
Scholars have identified approximately 400 distinct signs or symbols in the Harappan script. The average inscription is short, usually 4–5 signs in length.
Step 3: Elimination.
- (A) 100: Too low compared to actual findings.
- (B) 200: Still lower than accepted counts.
- (C) 300: Close but slightly underestimated.
- (D) 400: Most widely accepted approximate figure.
Step 4: Conclusion.
Hence, the Harappan script has approximately 400 symbols.
