Hi. Can you explain to me, how to find the answer for this question:

Median household income is $50,000 per year. The typical household spends about $125 per year on milk, which has an income elasticity of about 0.07. From this information, we can conclude that

(A) milk is a luxury.

(B) milk is a Giffen good.

(C) the income effect from a change in the price of milk is very large.
