How may a protective order be served to a respondent?

Serving a protective order to a respondent can be accomplished using a method that ensures proper legal notice is given. The option that indicates that it may be served in the same manner as a writ of conjunction or in open court is significant because it reflects established legal practices for serving legal documents.

This approach ensures that the respondent receives notice in a formal and recognizable setting, which is critical in legal situations where the response or compliance is necessary for protection. The importance of serving a protective order correctly cannot be overstated, as improper service might render the order ineffective or unenforceable.

While other methods like registered mail or direct personal delivery can be valid in various contexts, serving a protective order typically requires more formal processes to ensure the recipient is legally notified and can adequately respond. Therefore, the most reliable and legally accepted method as noted in the correct answer provides clarity and legitimacy in the enforcement of the order.
