Answer:
d. with puppy-dog eyes
Explanation:
The following misplaced group of words or modifiers are "with puppy-dog eyes", and when re-written it should look like this, "Having been discovered, with puppy-dog eyes Rover looked up at his owner"
I do believe the answer is b. introductions. why? well because an exposition is where everything is introduced. the characters, the setting, the time, etc.
It was the first English dictionary to use quotations from literature to illustrate word usage and development.
Hope this helps
