Explanation:

- Option 1: Value

- A value refers to principles or standards held by individuals or groups. While shaking hands can symbolize respect and friendliness, using the right hand is more about social norms than individual values.

- Option 2: Norm

- A norm is an established standard of behavior in a society. Extending the right hand for handshakes is a widely recognized norm in many cultures, signifying greeting or agreement.

- Option 3: Culture specialty

- Culture specialty implies a unique custom peculiar to a specific culture or community. While right-hand handshaking is common, it is not a peculiar specialty but rather a widespread practice.

- Option 4: None

- This option suggests that there is no association with extending the right hand for handshakes, which is inaccurate since it is a recognized practice.
