The correct answer is: a) Telugu literature.
Nannaya, Tikkana, and Errana are considered the ‘Kavitrayam’ (trinity of poets) of Telugu literature. They are the three most important poets in the history of Telugu literature, and their works are considered to be the foundation of Telugu literature.
Nannaya was the first poet to translate the Mahabharata into Telugu. He was born in the 12th century, and his work is considered to be the beginning of Telugu literature.
Tikkana was a poet who lived in the 14th century. He was a disciple of Nannaya, and he continued Nannaya’s work of translating the Mahabharata into Telugu.
Errana was a poet who lived in the 15th century. He was a disciple of Tikkana, and he completed Tikkana’s work of translating the Mahabharata into Telugu.
The works of Nannaya, Tikkana, and Errana are considered to be the foundation of Telugu literature. They are the three most important poets in the history of Telugu literature, and their works are still studied and enjoyed by Telugu people today.
The other options are incorrect because they are not the languages that Nannaya, Tikkana, and Errana wrote in. Sanskrit is an ancient Indian language, Tamil is a Dravidian language spoken in India and Sri Lanka, and Urdu is a Persian-influenced language spoken in India, Pakistan, and Bangladesh.
