Serena is evaluating two different models of hair dryers-Model A and Model B. She assigns belief ratings from 1 = very poor to 10 = very good and importance ratings from 10 = most important to 1 = least important. She sets a minimum mental cutoff point of 5 for all the features. Which of the following models is most likely to be selected by Serena if she employs the conjunctive rule to make the decision? $\begin{array} { | l | l | l | l | }
\hline \text { Attributes } & \text { Importance } & \text { Model A } & \text { Model B } \
\hline & & \text { Belief ratings } & \text { Belief ratings } \
\hline \text { Low price } & 8 & 7 & 4 \
\hline \text { Styling } & 9 & 6 & 7 \
\hline \text { Power efficiency } & 6 & 8 & 10 \
\hline
\end{array}$
A) Model A, as all the features have a rating above 5
B) Model B, as it has the highest power efficiency of 10
C) Model B, as it scores the highest on the styling criterion
D) Model A, as it scores highest on the low price attribute

Serena is using the conjunctive rule which requires all features to have a rating above the cutoff point. Therefore, in this case, Model A is most likely to be selected because all its features have a rating above 5. Model B may have some features with a rating above 5, but if any feature falls below the cutoff point, then the entire model is disqualified.
