The detail that best shows how the invitation to Rosings affects Mr. Collins's characterization is:
"Mr. Collins is surprised by the exclusive invitation."
This is evident when he said, "I confess that I should not have been at all surprised by her ladyship's asking us on Sunday to drink tea and spend the evening at Rosings."
This shows that he was surprised by the invitation, as he was not expecting it.
The title of the book is Pride and Prejudice.
JaneAusten wrote the book.
Hence, in this case, the correct answer is option C. "Mr. Collins is surprised by the exclusive invitation."
