Correct option is B
The main reason for the Chola penetration into Kalinga was the challenges posed by Maṣūnīdesa, who was the ruler of the Kalinga region. The Chola Empire, under Rajendra I, sought to expand its territory and secure the eastern coastline, which included Kalinga. This expansion was prompted by a desire to establish control over vital trade routes and expand the empire's influence. Maṣūnīdesa's resistance to Chola authority led to military action, which resulted in the Chola penetration into Kalinga.
