Answer:
Definitely B
Step-by-step explanation:
Because in A, pedro says he doesn't want to go, but there might be a reason behind that. Like maybe he was sick or busy. C is incorrect also because a mean person could've brought a pretty and well groomed dog, while a nice person could've brought a mean and dirty dog but that wouldn't tell anything about their personality except maybe their tastes. D is also incorrect because Pedro was just...there. He didn't do anything.
Hope this helps and have a great day!
