The production of a product consists of seven work elements. The desired output rate is 2 units per minute. The work elements and their precedence relationships follow. $$\begin{array} { | c | l | l | }
\hline \begin{array} { c }
\text { Work } \
\text { Element }
\end{array} & \text { Time (sec) } & \begin{array} { l }
\text { Immediate } \
\text { Predecessor(s) }
\end{array} \

2 & 16 & 1 \
3 & 12 & 2 \
4 & 14 & 3 \
5 & 18 & 2,4 \
6 & 12 & 5 \
7 & 20 & 4 \
\hline
\end{array}$$ Using the longest work- element time method, how many stations are required?
A) 2 stations
B) 3 stations
C) 4 stations
D) 5 stations
