Answer the Question on the Basis of the Following Production

Answer the question on the basis of the following production possibilities tables for two countries,Latalia and Trombonia: $\begin{array}{c}\quad\quad\quad\underline{\text {Latalia's Production Possibilities}}\\\begin{array}{lll}\\ \text {Pork (Tons) }\\ \text {Beans (Tons) }\end{array}\begin{array}{c}\underline{\text {A}}\\4\\0\end{array}\begin{array}{c}\underline{\text {B}}\\3\\5\end{array}\begin{array}{c}\underline{\text {C}}\\2\\10\end{array}\begin{array}{c}\underline{\text {D}}\\1\\15\end{array}\begin{array}{c}\underline{\text {E}}\\0\\25\end{array}\end{array}$
$\begin{array}{c}\quad\quad\quad\underline{\text {Trombonia's Production Possibilities }}\\\begin{array}{lll}\\ \text {Pork (Tons) }\\ \text {Beans (Tons) }\end{array}\begin{array}{c}\underline{\text {A}}\\8\\0\end{array}\begin{array}{c}\underline{\text {B}}\\6\\6\end{array}\begin{array}{c}\underline{\text {C}}\\4\\12\end{array}\begin{array}{c}\underline{\text {D}}\\2\\18\end{array}\begin{array}{c}\underline{\text {E}}\\0\\24\end{array}\end{array}$
