Explanations:The role of a chief minister in a state like West Bengal is crucial for the governance and administration of the state. The tenure of a chief minister can vary widely depending on the political situation, the state of the ruling party, and the overall political climate. In the context of West Bengal, several individuals have held the position of chief minister over the years, each with their own tenure length.
Prafulla Chandra Ghosh, who served as the chief minister of West Bengal from 1947 to 1948, holds the distinction of being the shortest serving chief minister. His tenure was brief, lasting only a year, which makes him the correct answer to the question. This short tenure can be attributed to the political instability and the transition period that India was going through at the time of independence.
Other chief ministers, such as Siddharth Shankar Ray, Ajay Kumar Mukherjee, and Bidhan Chandra Roy, served for longer periods. Siddharth Shankar Ray served twice, from 1977 to 1979 and again from 1980 to 1982, making his tenure longer than a year. Ajay Kumar Mukherjee served from 1996 to 1997, which is also longer than Prafulla Chandra Ghosh's tenure. Bidhan Chandra Roy, on the other hand, had a very long tenure, serving from 1948 to 1962, which is significantly longer than the others.
