Which one of the following famous ruler is called as 'Father of Inscriptions'?

Ashoka is known as the 'Father of Inscriptions' due to the extensive number of inscriptions he issued across his empire.

These inscriptions were inscribed on rocks and pillars and were written in languages like Prakrit and Brahmi script.

Ashoka's inscriptions are significant as they provide detailed insights into his administration, his promotion of Buddhism, and his moral code known as Dhamma.

While Samudragupta is known for the Prayag Prashasti, Ashoka's contributions through his inscriptions have a far-reaching impact on Indian history and culture.
