Which of these choices is a positive consequence of the endangered species act with respect to gray wolves? a. the law has been expensive to enforce. b. the wolf population has recovered after being near extinction. c. the law has angered many ranchers. d. the reintroduced wolves are more aggressive than the original wolves.

The correct answer is-

B. The wolf population has recovered after being near extinction.

Grey wolves became endangered ( came in a danger of getting eliminated completely/ extinct) because people considered them pests as they thought that they were destroying their livestocks. So, people took their lands and killed them.

The population of gray wolf was declined to the extent that it was declared endangered by the mid 1900s in the lower 48 states of the US (United States). Due to Endangered Species Act ( that provided protection to increase their number), the wolf population has recovered after being near extinction.

Thus, option B) is the right answer.

d.
