Explanation:

- Organisational Policy: This refers to the rules and regulations within a company. It might influence communication but isn't a semantic barrier.

- Lack of Attention: This happens when someone isn't fully engaged in the conversation, leading to misunderstandings. It's a psychological barrier, not a semantic one.

- Technical Jargon: This includes complex terms that are difficult for non-experts to understand. It often prevents clear communication and is indeed a semantic barrier.

- Status: Differences in rank or authority might affect how freely people communicate, creating a social barrier instead of a semantic one.

Your answer is right.
