Final Answer :
B
Explanation :
The increase in the number of Canada geese in the United States is primarily attributed to an increase in the carrying capacity for nonmigratory birds. This means that the environment can support a larger population of these birds, likely due to changes in habitat, availability of food, or reduction in predators or competition.
