Option a is the correct answer. The work composed by Krishnadevaraya on statecraft in Telugu is "Amuktamalyada." Krishnadevaraya, the renowned emperor of the Vijayanagara Empire, was not only a patron of arts and literature but also a talented poet himself. "Amuktamalyada" is a Telugu poem that narrates the story of the marriage between the divine princess Amuktamalyada and the earthly king Vishnuchitta, symbolizing the union of spiritual and temporal realms. While the poem primarily focuses on the themes of love and devotion, it also contains valuable insights into governance, administration, and statecraft.
