The cross price elasticity of demand is calculated as the percentage change in quantity demanded of good Y divided by the percentage change in price of good X. When PX rises from $10 to $12, QY changes from 90 to 50. The percentage change in QY is $(-40/90) \times 100 = -44.44\%$ and the percentage change in PX is $(2/10) \times 100 = 20\%$. Thus, the cross price elasticity is $-44.44\% / 20\% = -2.22$, which is not listed. However, if we consider the change from 60 to 50 for QY (as the table suggests a different interpretation), the calculation would be $(-10/60) \times 100 = -16.67\%$, leading to $-16.67\% / 20\% = -0.83$, which is also not listed. The closest option is C) +0.58, which suggests a calculation error or misinterpretation in the options provided.
