To determine the correct type of communication involved in Andrea delivering her Valedictory Speech, we can analyze the options provided:

1. Interpersonal - This involves direct communication between two people. It does not apply here as Andrea is addressing a larger audience.
2. Dyadic - This refers to a conversation between two individuals. Again, this is not applicable for a speech delivered to an audience.
3. Public - This type of communication is directed towards a group with one person speaking. Given that Andrea is delivering a speech in a formal setting, this seems to be the correct option.
4. Interpersonal (small group) - This typically involves a small group of people communicating with one another. This is also not fitting for the context of a valedictory speech.
5. Mass - This refers to communication intended for a large audience, typically through media channels. While speeches can reach mass audiences, this term usually applies to media formats rather than live speeches.
6. Intrapersonal - This is communication within oneself, which does not fit the scenario of delivering a speech.

Final Answer

The correct answer is Public communication, as Andrea is delivering her Valedictory Speech to an audience.
