- Cultural diffusion is the process through which cultural traits, ideas, or innovations spread from one culture to another.

- This can be through direct contact, trade, migration, or media.

- Correct Answer

- Parallelism:

- This refers to the development of similar traits or features in different cultures independently, rather than through contact or diffusion.

- Evolution:

- In a cultural context, evolution refers to the gradual development of cultural traits over time within a society.

- It doesn't specifically refer to the spread between societies.

- Pluralism:

- This involves a society where multiple distinct cultural or ethnic groups coexist and maintain their unique traditions.

- It does not inherently involve the spreading of traits to new societies.
