单选题

Scientist：More than 1, 000 large asteroids regularly cross the Earth's path．Even though the probabil-ity of one colliding with the Earth is extremely slight, we should do whatever we can to reduce that probability since any such collision would be catastrophic．The best way to avoid such a disaster is to deflect the asteroids．The only known way of deflecting asteroids is by hitting them with nuclear weapons that would be stored in space stations.The scientist’s claims are structured so as to lead to which of the following conclusions？

A、 Nuclear technology is the only technology that can plausibly be used to prevent natural catastrophes．
B、 Nuclear weapons should be deployed in space．
C、 No catastrophe has yet been caused by the collision of an asteroid with the Earth
D、 The 1, 000 large asteroids that cross the Earth's path pose only an extremely slight risk of colliding with the Earth．
E、 There is currently no acceptable use to which nuclear weapons can be put, aside from protecting the Earth from asteroids．
