Step-by-step explanation:
In order to understand the problems that separate us, we should engage with the perceptions of others. This involves recognizing that our perceptions are unique to us due to various factors such as beliefs, values, and experiences, and may not present a full or complete picture of the world. Additionally, we should pay attention to non-verbal elements of communication for better understanding, as our sensory input is not always a perfect reflection of reality. It's also imperative to compare our perceptions with others to gain broader perspectives and reduce misunderstandings. Therefore, the answer to the student's question is C. b, c, d.
