Task: Question Answering
Input (English): Question: Thurston wrote an important seven-digit phone number on a napkin, but the last three numbers got smudged. Thurston remembers only that the last three digits contained at least one zero and at least one non-zero integer. If Thurston dials 12 phone numbers by using the readable digits followed by 12 different random combinations of three digits, each with at least one zero and at least one non-zero integer, what is the probability that he will dial the original number correctly?

 Option A: 1/9

 Option B: 10/243

 Option C: 2/45

 Option D: 10/271

 Option E: 1/1000000
Output (English): Option C
