The Table Below Shows the Payoffs to the Running of Negative

The table below shows the payoffs to the running of negative and positive political ads by two candidates.The payoffs are the percentage increase or decrease in the number of voters willing to vote for the candidate as a result of the campaign styles. $\begin{array}{c}\quad\quad\quad\quad\quad\quad\quad\quad\quad\quad\quad\text { Republican Candidate }\\\text { Democratic Candidate }\begin{array}{|l|l|l|}\hline & \text { Positive Campaign } & \text { Negative Campaign } \\\hline {\text { Positive Campaign }} & \begin{array}{l}\text { Democrat } 0 \% \\\text { Republican: } 0 \%\end{array} & \begin{array}{l}\text { Democrat:-3\% } \\\text { Republican: }+3 \%\end{array} \\\hline {\text { Negative Campaign }} & \begin{array}{l}\text { Democrat: }+5 \% \\\text { Republican: }-5 \%\end{array} & \begin{array}{l}\text { Democrat }-2 \% \\\text { Republican: }-2 \%\end{array} \\\hline\end{array}\end{array}$
Refer to the figure above.Suppose that the Republican candidate tells the Democratic candidate that he intends to run a positive campaign.The likely result is that:

A) both candidates will run a positive campaign.
B) the Republican candidate will run a positive campaign,but the Democratic candidate will run a negative campaign.
C) the Republican candidate will eventually turn to negative campaigning because the Democratic candidate will run a negative campaign.
D) the Democratic candidate will trust the Republican candidate's statement and run a positive campaign,but the Republican candidate will run a negative campaign.
