Party A must decide whether or not to launch a smear campaign against the Party B candidate; he knows Party B will not be the first to go on the offensive. If he does not launch this campaign, his win is 0 and Party B's win is 0 as well. If he throws it, there are two possibilities: either Party B replies and then the gain of Party A is -10 and that of Party B 10, or Party B does not reply and then the gain of Party A is 10 and that of Party B -10. What does Party A decide?

Please choose an answer:

a. None of the above.

b. Party B launches a smear campaign against Party A.

c. Party A launches a smear campaign against Party B.

d. Party A is not launching a smear campaign against Party B.
