The correct answer is B) Mon-Khmer branch of Austro-Asiatic sub-family.
The Khasi language is an indigenous language spoken by the Khasi people in the state of Meghalaya in India, as well as by a smaller population in neighbouring Bangladesh. Linguistically, Khasi belongs to the Mon-Khmer branch of the Austro-Asiatic language family. The Austro-Asiatic family is dispersed across Southeast Asia and parts of India.
Other branches of the Austro-Asiatic family include the Munda languages, spoken primarily in central and eastern India (e.g., Santali, Mundari, Ho), and various languages spoken in Southeast Asia (e.g., Khmer, Vietnamese, Mon). The Sino-Tibetan language family, on the other hand, includes languages like Tibetan, Burmese, and many languages spoken in Northeast India such as Bodo, Manipuri (Meitei), and various tribal languages.
