Answer:
The correct option is D: Ambiguous sentences; unaware
Explanation:
Donald MacKay conducted a study in which his participants were made to attend to ambiguous sentences and at the same time were being presented with certain priming words or biasing words on the unattended ears. It was clearly seen from the results of this study that the meaning of the priming words affect the way that the participants understood the messages, despite the participants being unaware of that word.
