Answer:
The correct option is
D. The professor is correct because neither the number of favorable outcomes nor total outcomes can be determined for this event.

The probability is how likely an event can happen. To find the probability we need to use the below formula:
![Probability=(Favorable-outcomes)/(Total-outcomes)](https://img.qammunity.org/2020/formulas/mathematics/college/vki2gzl7hx1l6y0l40xhi0dp72x0xd7ln9.png)
In the given, neither we given outcomes which are favorable to the happening of nuclear war, nor we are given outcomes which are total outcomes for the given experiment. Therefore, the Professor is correct because neither the number of favorable outcomes nor the total outcomes can be determined for this event.
