plz help me solve this

Suppose there are two consumers, A and B. There are two goods, X and Y. There is a TOTAL of 8 units of X and a TOTAL of 8 units of Y. The consumers' utility functions are given by: UA(X,Y) = 2X + Y UB(X,Y) = X*Y2 Which of the following allocations is Pareto Efficient? O Consumer A gets 1 units of X and 4 units of Y, and Consumer B gets 7 units of X and 4 units of Y. O None of these allocations are Pareto Efficient. O Consumer A gets 3 units of X and 8 units of Y, and Consumer B gets 5 units of X and 0 units of Y. O Consumer A gets 8 units of X and 8 units of Y, and Consumer B gets 0 units of X and 0 units of Y. O Consumer A gets 4 units of X and 4 units of Y, and Consumer B gets 4 units of X and 4 units of Y
