Answer: d. income elasticity of demand for that good.

Explanation:

A good is a normal when an increase in income leads to an increase in demand for the good and inferior when an increase in income leads to a decrease in demand for the good. Thus, to determine whether the good is normal or inferior we use income elasticity of demand for that good. If income elasticity is positive the good is a normal good. If income elasticity is negative, the good is inferior.
