To determine the author's main purpose in the article, we must consider the context and content of the article.
If the article discusses increasing interest and research related to the phenomenon of déjà vu, option A would be correct.
If it focuses on clarifying misunderstandings or myths surrounding déjà vu, then option B would be the best choice.
If the article aims to demonstrate how widespread déjà vu is among people, then option C would apply.
Lastly, if it emphasizes the significance of acknowledging and reflecting on déjà vu experiences, option D would be appropriate.
Without additional context about the article's content, it's challenging to definitively select the best answer. However, based on the given options, the one that often aligns with many academic or analytical pieces about phenomena like déjà vu tends to be B (to explore common misconceptions about déjà vu) as many articles aim to clarify misunderstandings about such experiences.
Ultimately, the best choice depends on the specific focus of the article.
