The correct answer is: b) Roman alphabet.
The Mizo language is written in the Roman alphabet, with some additional letters. The Roman alphabet is a writing system that is used for many languages around the world, including English, Spanish, French, and German. It is a phonetic alphabet, which means that each letter represents a sound. This makes it a very versatile writing system, as it can be used to write many different languages.
The Roman alphabet was originally developed in ancient Rome. It was based on the Etruscan alphabet, which was in turn based on the Greek alphabet. The Roman alphabet was adapted to write Latin, the language of ancient Rome. It has since been adapted to write many other languages, including Mizo.
The Mizo language is spoken by about 800,000 people in Mizoram, India, and in neighboring areas of Myanmar. It is a member of the Kuki-Chin language family. The Mizo language is tonal, which means that the pitch of your voice can change the meaning of a word. It is also a verb-initial language, which means that the verb comes at the beginning of the sentence.
The Roman alphabet is a very efficient writing system. It is easy to learn and use, and it can be used to write many different languages. This makes it a good choice for a writing system for the Mizo language.
