The correct answer is - A. Romans adopted Greek gods but gave them new names.
The Romans and the Greeks interacted for a long time. The Greeks developed as a civilization earlier than them, so it was natural for the Romans to adopt some traits of a civilization that was more advanced and they were familiar with. They did this with the gods. The Romans adopted the Greek gods, and even though they kept their characteristics, they decided to change their names, so there was a situation where both civilization had the total same gods, but they had different names for them. One of the many examples is the Greek goddess Aphrodite, which the Romans named as Venus.
