Explanation:

- Mautam: This is the correct answer. Mautam refers to the cyclical famines caused by the flowering of the Melocanna baccifera bamboo every 48 years, leading to a rat population boom in Northeast India, particularly in Mizoram. The rats destroy crops, resulting in famine.

- Doji Bara: Also known as the Skull Famine, it happened in the late 18th century in parts of India but is unrelated to bamboo flowering.

- Chalisa: Refers to the famine in 1783-84 in North India, not related to bamboo or rats.

- Upper Doab: Refers to an area in India but not specifically associated with a historical famine tied to bamboo flowering.
