The correct answer is option 4, Mesopotamian. Cylindrical stone seals were indeed used in the Mesopotamian civilization, which existed in ancient Iraq and parts of Syria and Iran.

Mesopotamian seals were typically made of stone and had a cylindrical shape with intricate engravings or carvings on their surfaces. These seals were used for various purposes, such as marking ownership on clay tablets, documents, and other objects.

The seals were rolled across damp clay surfaces, leaving behind unique impressions or imprints. These impressions served as a form of identification or authentication. This practice was common in administrative and legal transactions, allowing individuals to prove their authority or ownership.

Harappan, Egyptian, and Roman civilizations did have their own forms of seals and stamping practices, but cylindrical stone seals were not commonly used in these civilizations. Therefore, options 1, 2, and 3 are incorrect.

Alert - correct answer should be 1 Harappan.
