Explanation: To understand who the longest-serving Chief Minister of Mizoram is, it is essential to delve into the political history of the state. Mizoram, a state in northeastern India, has had several Chief Ministers since its formation. The Chief Minister is the head of the state government and is elected by the members of the Legislative Assembly.
Lal Thanhawla, a prominent political figure in Mizoram, has served as the Chief Minister for the longest period. He first took office in 1998 and continued until 2003. He then returned to office in 2008 and served until 2013. This makes his total tenure as Chief Minister the longest among all Chief Ministers of Mizoram.
Zoramthanga, another significant political figure, served as the Chief Minister but for a shorter period compared to Lal Thanhawla. His tenure was not as extensive, and he did not hold the position for as long as Lal Thanhawla did.
Sailo, while a notable political leader, served as the Chief Minister for a brief period. His tenure was not as long as that of Lal Thanhawla, and he did not hold the position for as many years.
Laldenga, a key figure in Mizoram's political landscape, also served as the Chief Minister. However, his tenure was shorter than that of Lal Thanhawla. Laldenga's contributions to Mizoram's political history are significant, but in terms of the length of service as Chief Minister, he does not surpass Lal Thanhawla.
In conclusion, Lal Thanhawla is the longest-serving Chief Minister of Mizoram, with a total tenure that spans more years than any other Chief Minister in the state's history. This makes him the correct answer to the question. Understanding the political history and the terms of office for each Chief Minister is crucial to answering such questions accurately.
