Correct option is C
Bahadur Shah I, who reigned from 1707 to 1712, was nicknamed 'Shah-i-Bekhabar' (meaning "The Heedless King") due to his lack of political acumen and inability to maintain a stable empire after the death of Aurangzeb. His reign marked the beginning of the decline of the Mughal Empire, as he struggled to manage internal revolts and external threats.
