Answer the Question on the Basis of the Following Production

Answer the question on the basis of the following production possibilities data for two countries,Alpha and Beta,which have populations of equal size. $\begin{array}{c}\quad\quad\underline{\text { Alpha's Production Possibilities }}\\\begin{array}{lll} \\ \text {Fish (Tons) }\\ \text {Chips (Tons) } \end{array}\begin{array}{c}\underline{\text {A }}\\ 80 \\0\end{array}\begin{array}{c}\underline{\text {B }}\\ 60 \\5\end{array}\begin{array}{c}\underline{\text {C }}\\ 40 \\10\end{array}\begin{array}{c}\underline{\text {D }}\\20 \\15\end{array}\begin{array}{c}\underline{\text {E }}\\0 \\20 \end{array}\end{array}$

$\begin{array}{c}\quad\quad\underline{\text { Beta's Production Possibilities }}\\\begin{array}{lll} \\ \text {Fish (Tons) }\\ \text {Chips (Tons) } \end{array}\begin{array}{c}\underline{\text {A }}\\240 \\0\end{array}\begin{array}{c}\underline{\text {B }}\\ 180 \\10\end{array}\begin{array}{c}\underline{\text {C }}\\120 \\20\end{array}\begin{array}{c}\underline{\text {D }}\\60 \\30\end{array}\begin{array}{c}\underline{\text {E }}\\0 \\40 \end{array}\end{array}$

The given data show that:

A) Beta has a comparative advantage in producing chips.
B) Alpha has a comparative advantage in catching fish.
C) Alpha is subject to constant costs and Beta is subject to increasing costs.
D) Beta is more efficient than Alpha both in catching fish and in producing chips.
