Answer is Wrong!
Answer is Right!
The correct answer is: A. Santhali language.
Ol Chiki is a writing system used for the Santhali language. It was developed in the 19th century by Pandit Raghunath Murmu, a Santhali scholar. Ol Chiki is a phonetic script, which means that each symbol represents a single sound. This makes it easy to learn and use. Ol Chiki is now the official script of the Santhali language in India. It is also used by Santhali people in Bangladesh, Nepal, and Bhutan.
The other options are incorrect because they are not languages that use the Ol Chiki script. Maithili is a language spoken in India and Nepal. Assamese is a language spoken in India.
