Correct option is B
Balaji Bajirao, also known as Nana Saheb, was the Peshwa of the Maratha Empire during the Third Battle of Panipat in 1761. Balaji Bajirao was the son of the legendary Peshwa Baji Rao I and played a pivotal role in expanding the Maratha Empire. However, the Third Battle of Panipat, fought between the Marathas and the Durrani Empire led by Ahmad Shah Abdali, ended in a catastrophic defeat for the Marathas.
The battle took place on January 14, 1761, and is considered one of the largest and bloodiest fought in the 18th century.
The loss at Panipat significantly weakened the Maratha Empire, and it took several years for the empire to regain its strength.
