I need help with this practice question by explaining the steps to figuring out the correct question.

20. Anne ran a regression to estimate qx = D, + D, In(Px ) + D, In(Py ) + D; In(Pz ) + b, In(Inc), where denotes quantity of "good x," px denotes price of "good x," p, denotes price of "good y," pz denotes price "good z," and Inc denotes per capita Income in the market for "good x." Her estimated coefficient values bo =5.62, b = -1.35, b, = -0.45, b, = 0.68, and b, =-0.37 . These results would suggest that A. "good x" is an inferior good. B. "good x" is a complement to "good y." C. "good x" is a complement to "good z." D. More than one (perhaps all) of the above answers is correct
