Given the Following Table Showing Various Combinations of Goods X

Given the following table showing various combinations of goods X and Y that bring equal satisfaction to an individual consumer:
$\begin{array} { l r } \text { good X } & \text { good Y } \\\hline 2 \text { units } & 10 \text { units } \\3 \text { units } & 9 \text { units } \\4 \text { units } & 6 \text { units } \\5 \text { units } & 2 \text { units }\end{array}$
In this table, as the individual consumes a greater amount of X, a __________ amount of good Y is given up for each additional unit of good X. This pattern suggests that, as more of good X is consumed and less of good Y is consumed, the ratio MU_X/MU_Y is __________.

A) larger; increasing, which contradicts economists' usual expectations
B) larger; decreasing, which conforms to economists' usual expectations
C) smaller; increasing, which contradicts economists' usual expectations
D) smaller; decreasing, which conforms to economists' usual expectations
