请教GWD的逻辑题

Some species of Arctic birds are threatened by recent sharp increases in the population of snow geese, which breed in the Arctic and are displacing birds of less vigorous species. Although snow geese are a population quarry for hunters in the southen regions where they winter, the hunting season ends if and when hunting has reduced the population by 5 percent, according to official estimates. Clearly, dropping this restriction would allow the other sprecies to recover.

Which of the following, if true, most seriously undermines the argument?

A. Hunting limits for snow geese were imposed many years ago in response to a sharp decline in the population of snow geese.

B. It has been many years since the restriction led to the hunting season for snow geese being closed earlier than the scheduled date.

C. The number of snow geese taken by hunters each year has grown every year for several years.

D. As their population has increased, snow geese has reconolized wintering grounds that  they had not used for several seasons.

E. In the snow goose's winter habitats, the goose faces no significant natural predation.

答案选的是B，但是我不太懂中间的逻辑是怎么样的，我选的D，请问这个有什么问题呢？
