Solution:
Archaeologists have discovered thousands of seals, usually made of steatite, and occasionally of agate, chert, copper, faience and terracotta, with beautifulfigures of animals, such as unicorn bull, rhinoceros, tiger, elephant, bison, goat, buffalo, etc. at various sites of Indus valley.
The purpose of producing seals was mainly commercial .
Hence, statement 1 is correct.
It appears that the seals were also used as amulets, carried on the persons of their owners, perhaps as modern- day identity cards .
Every seal is engraved in a pictographic script which is yet to be deciphered. They all bear a great variety of motifs, most often of animals including those of the bull, with or without the hump, the elephant, tiger, goat and also monsters.
