Assertion (A) states that we have much more information about Cholas than their predecessors. This is true because the Chola period is rich in historical sources. Reason (R) states that Chola rulers adopted the practice of having inscriptions written on temple walls giving historical narratives of their victories. This is also true and is a defining characteristic of Chola rule, particularly the extensive use of prasastis (eulogies) inscribed on temples detailing the king's achievements, conquests, and administration.
