Consider the Following Trip Matrix for a Layout Problem Having

Consider the following trip matrix for a layout problem having four departments:
$$\begin{array} { | l | l | l | l | l | } \hline & \mathrm { A } & \mathrm { B } & \mathrm { C } & \mathrm { D } \\\hline \mathrm { A } & - & 4 & 5 & 0 \\\mathrm { BCD } & & - & 0 & 3 \\& & & - & 4 \\\hline\end{array}$$
Assuming equal- sized departments and rectilinear distance, which of the following block plans is best?

A)
$\begin{array} { | c | c | } \hline \mathrm { A } & \mathrm { C } \\\hline \mathrm { D } & \mathrm { B } \\\hline\end{array}$
B)
$\begin{array} { | c | c | } \hline A & B \\\hline C & D \\\hline\end{array}$
C)
$\begin{array} { | c | c | } \hline A & D \\\hline C & B \\\hline\end{array}$
D)
$\begin{array} { | l | l | } \hline A & D \\\hline B & C \\\hline\end{array}$
