The correct answer is (b), Rajaram.
Shambhuji was the elder son of Shivaji Maharaj, the founder of the Maratha Empire. He was killed by Aurangzeb’s forces in 1689. Rajaram was Shambhuji’s younger son. He succeeded his father as the Maratha leader in 1689. He ruled the Maratha Empire until his death in 1700.
Jijabai was the mother of Shivaji Maharaj and grandmother of Rajaram. She was a strong and influential figure in the Maratha Empire. She played a key role in the early years of the empire, and her advice and support were invaluable to her son and grandson.
Tarabai was the wife of Rajaram. She was a powerful and ambitious woman. After Rajaram’s death, she ruled the Maratha Empire as regent for her son, Shivaji II. She was a capable ruler, but she was also ruthless and unpopular. She was eventually overthrown by her son in 1707.
