Answer the Question on the Basis of the Following Production

Answer the question on the basis of the following production possibilities data for Gamma and Sigma.All data are in tons. Gamma's production possibilities: $\begin{array}{llcc}&\underline{\text { A } }&\underline{\text {B}}&\underline{\text { C} } &\underline{\text { D } }&\underline{\text {E}}\\\text { Tea } &120&90&60&30&0\\\text { Pots}&0&30&60&90&120\end{array}$
Sigma's production possibilities: $\begin{array}{llcc}&\underline{\text { A } }&\underline{\text {B}}&\underline{\text { C} } &\underline{\text { D } }&\underline{\text {E}}\\\text { Tea } &120&90&60&30&0\\\text { Pots}&0&30&60&90&120\end{array}$
Refer to the given data.What are the limits of the terms of trade between Gamma and Sigma?

A) 1 tea = 2 pots to 1 tea = 6 pots
B) 1 tea = 3 pots to 1 tea = 6 pots
C) 1 tea = 2 pots to 1 tea = 3.5 pots
D) 1 tea = 1 pot to 1 tea = 3 pots
