Who was the last ruler of the Pallava dynasty?
A. Parameswara Varman
B. Narasimhavarman
C. Aparajitavarman
D. Mahendravarman

Hint- He was the last ruling member of his house; he was killed in 897 CE. In 880 CE he had defeated and killed Varagunavarman II. The Pallava dynasty's rule came to an end with the death of this king

Step by step solution- The Pallavas emerged as a daunting power in the South around the fourth century AD and at the same time they were at the height of their power in the seventh century AD as well. The Pallava dynasty was able to sustain its rule for approximately 500 years. They had constructed great cities, centers of learning, temples, and sculptures and also influenced a large area of Southeast Asia in culture.
After Mahendravarman II, his son Parameswaravarman had become the king. In his rule, Kanchipuram was occupied by the Chalukyas. Nrupatunga was a very important king who had defeated a Pandya king. There were a few other rulers as well.
The last ruler of the Pallava dynasty was "Aparajita Arman''. He was a king of the Pallava dynasty who had been killed in battle with the Cholas. The Cholas under Aditya I initially was minor allies of the Pallavas, but afterward attacked them, defeated and killed Aparajitavarman, their former ruler. The Pallava rule at Tondaimandalam came to an end.
Thus, option C is the right answer.

Note- A depiction of Somaskanda on the rear wall of the sanctum of a temple commissioned by him in Tiruttani is regarded as the last known use of that stylistic tradition.In 885 he transferred the rule of Thanjavur to his ally and vassal Aditya I as a reward for his contribution to the victory at Thirupurambiyam.
