The correct answer is B.
A is incorrect because the two nations were in a Cold War at the time, and the whole point of the Cold War was to not go ballistic (mutually assured destruction) and destroy one another. C is incorrect because the CIA was already formed in 1947, and this specific event takes place in the late 1950s. Lastly, D is incorrect because NASA was formed because of the creation & success of Sputnik.
Hope this helps!
