The correct answer is: d) All of the above.
Mizo is a Sino-Tibetan language spoken by the Mizos, an ethnic group native to the Indian state of Mizoram and the Chittagong Hill Tracts of Bangladesh. The language is closely related to the Kuki languages, and is also influenced by neighboring languages like Bengali and Chakma.
English was introduced to Mizoram during the British colonial period, and has since become a major language of education and administration in the state. Hindi has also been gaining popularity in Mizoram in recent years, due to its status as an official language of India and its use in popular media.
The influence of these other languages can be seen in the Mizo language, both in terms of vocabulary and grammar. For example, many Mizo words have been borrowed from Bengali and Chakma, and the grammar of the language has been influenced by English.
The influence of these other languages has led to some debate among Mizo linguists about the future of the language. Some argue that the language is becoming too mixed with other languages, and that it is losing its unique identity. Others argue that the influence of other languages is inevitable, and that the Mizo language should be allowed to evolve and adapt to its new environment.
