The correct identification of civilizations with their classification is:
A. Greece and Rome are classical civilizations
Explanation:
- Greece and Rome are widely recognized as classical civilizations due to their significant contributions to art, philosophy, government, and science.
- Egypt and Indus are often classified as river valley civilizations but are not typically referred to as classical civilizations in the same context as Greece and Rome.
- Mesopotamia and Greece do not both fit under the river valley civilization classification, as Greece is not located in a river valley but rather is influenced by its geography.
- West Africa is not classified as a classical civilization in the same way as Greece and Rome, and China, while it has classical periods, is not typically grouped with West Africa.
Thus, the most accurate option is A.
