My answer:
I think clearly confused means everyone looks at you and it's obvious that you are confused most likely because of your facial expressions or maybe because of what you said and it could also be because you're acting nervous like fidgeting your hands.
Example sentence:
"Tasha, clearly confused, stared at Mrs. Groban—she didn’t know how to answer the question. Her mouth gaped open and moved up and down, but she could not find any words to articulate."
Hope this is helpful!
