Explanation:

Let’s break down the options:

- Vishnu Sharma: He’s best known as the author of the ancient collection of animal fables called the Panchatantra. Not related to the Ramcharitmanas.

- Valmiki: He wrote the original Sanskrit Ramayana, not the Ramcharitmanas.

- Veda Vyasa: This sage is credited with compiling the Mahabharata, another massive ancient epic. Also not the Ramcharitmanas.

- Tulsidas : He is the poet-saint who wrote the Ramcharitmanas in the 16th century, retelling the story of Rama in Awadhi, which is a form of Hindi. His version is deeply revered in North India.

So yes, Tulsidas is the right answer here, and you nailed it.
