Answer and Explanation:
Two goods are said to be complementary goods if an increase in the price of a particular one leads to a commensurate decrease in the demand that buyers placed for the other one.
A good is said to be a normal good if the reason for an increase in demand is due to an increase in the income of the buyers.
A good is said to be an inferior good if there is a decrease in demand even though the buyers have experienced increase in their income.
