The correct answer is: a) Hmar, Mara, and Lai.
The Mizo language is a Sino-Tibetan language spoken by the Mizo people in Northeast India and in neighboring areas of Myanmar. It is the official language of the state of Mizoram in India. The Mizo language has several dialects, the most important of which are Lusei, Hmar, Mara, and Lai.
The Lusei dialect is the most widely spoken dialect of Mizo, and is the standard dialect used in education and government. The Hmar dialect is spoken by the Hmar people, who live in the states of Mizoram and Manipur in India. The Mara dialect is spoken by the Mara people, who live in the state of Mizoram in India. The Lai dialect is spoken by the Lai people, who live in the states of Mizoram and Manipur in India.
The other options are incorrect because they do not include any major dialects of Mizo. Option b, Chakma, Ralte, and Bawm, includes three dialects of Chakma, which is a different language from Mizo. Option c, Pawi, Pang, and Zote, includes three dialects of Pawi, which is another different language from Mizo. Option d, Garo, Khasi, and Jaintia, includes three languages that are spoken in the northeastern states of India, but they are not dialects of Mizo.
