The correct answer is:
Both civilizations used bulls to symbolize religion.
Explanation: The ancient silver sculpture of a kneeling bull and the terracotta vessel in the form of a bull’s head both suggest that the bull held symbolic significance within the cultural practices of river valley civilizations and later classical civilizations. Bulls were often associated with strength, fertility, and were revered in many cultures as religious symbols. This connection indicates how art from both periods reflects shared themes in their religious beliefs and practices.
