Correct Answer: Thalavaipuram Copper Plates

Solution : The correct option is Thalavaipuram Copper Plates

The Thalavaipuram copper plates contained information about the land measurements of the Second Pandyan Empire. The Thalavaipuram copper plates are a series of 12 copper plates issued by Sundara Pandya, the Pandyan ruler, in 1018 CE. Six distinct land measurements are mentioned on the Thalavaipuram copper plates: thoni, veli, anai, kuram, kani, and nilam.  The Second Pandyan Empire's land measurements were based on the old Tamil land measurement system. When the Thalavaipuram copper plates were issued in the 10th century CE, this technique was still in use.
