Answer:
The meaning of this excerpt is:
A. Perrault is fighting stray dogs that have invaded the campsite looking for food.
Step-by-step explanation:
This is an excerpt from "The Call of the Wild", by author Jack London.
There are some clues in the passage that help us find the correct answer. Let's highlight them:
An oath from Perrault, the resounding impact of a club upon a bony frame, and a shrill yelp of pain, heralded the breaking forth of pandemonium. The camp was suddenly discovered to be alive with skulking furry forms,—starving huskies, four or five score of them, who had scented the camp from some Indian village. They had crept in while Buck and Spitz were fighting, and when the two men sprang among them with stout clubs they showed their teeth and fought back. They were crazed by the smell of the food. Perrault found one with head buried in the grub-box.
The bolded parts highlight the clues we need. Stray dogs, four or five of them, could smell the food that was kept in the camp. They crept in and, upon being discovered, were attacked by Perrault with a club.
