Correct Option
The correct option is 2 only.
Explanation
Harappan inscriptions are predominantly short and occur on a variety of archaeological objects.
The script remains undeciphered, which prevents definitive conclusions regarding its language, content or exclusive association with any particular social group.
Statement-wise Analysis
- Statement 1: Incorrect. Harappan writing has been found on seals, sealings, pottery, copper tablets, tools and other objects; it was not confined exclusively to steatite seals.
- Statement 2: Correct. Most inscriptions consist of only a few signs, and the longest known inscription contains approximately 26 signs.
- Statement 3: Incorrect. Archaeological evidence does not establish that writing was strictly restricted to a priestly class. Such a conclusion cannot be drawn from an undeciphered script.
Key Takeaway: Harappan inscriptions were brief and appeared on diverse objects, while their users and contents remain uncertain because the script has not been deciphered.
