In Mesopotamia clay tablets were mainly used for what?

For writing and record keeping

Clay tablets were the main writing material in Mesopotamia because wet clay was easily available near the rivers. Scribes pressed a wedge-shaped tool into the soft clay to make cuneiform signs. After drying or firing, the tablets became durable records. They were used for accounts, trade transactions, laws, taxes, property matters, letters, and other administrative information.

Option A is correct because writing and record keeping were the principal uses of Mesopotamian clay tablets. The tablets could preserve information needed by temples, palaces, and merchants over time. Glass making, making sails, and mummification required different materials and practices. Thus, the historical evidence about cuneiform and administration clearly supports the first option.
