Which one of the following is the language of the famous political treatise…

A literary work's language is fixed by the actual author who composed it, not by the work's genre, its subject legend, or a general convention about that genre. To identify the language of a specific medieval Indian text, one must identify who wrote it and in which language that author chose to write, rather than assuming a default language for its type.

Amuktamalyada was composed by Krishnadevaraya, the Vijayanagara emperor (reigned 1509-1529 CE), who was celebrated as “Andhra Bhoja” for his patronage and personal authorship of Telugu literature. Although the work narrates the Tamil Alvar legend of Andal (Goda Devi) and her devotion to Vishnu, and although it doubles as a niti (statecraft) treatise advising a king on governance, Krishnadevaraya composed the actual verses in Telugu, making it one of the celebrated works of Telugu prabandha literature.

• Sanskrit was the classical scholarly language typically used for shastra and niti literature across India, but Krishnadevaraya chose a different language for this particular composition.

• Tamil is the language of the original Andal legend from the Alvar bhakti tradition that the work retells, but the retelling itself was composed in a different language.

• Kannada was another language actively patronized at the Vijayanagara court, but it was not the language the emperor used for this treatise.

• Telugu is the language in which Krishnadevaraya actually composed this treatise, confirmed by government and academic literary records.

Hence, the treatise is correctly identified as a Telugu composition.
