:A.If income increases and desk lamps are normal goods

.B.If floor lamps are substitute goods for desk lamps, the price of floor lamps increases

D.If desks are a complementary good for desk lamps, the price of desks decreases.

Explanation:

A normal good is a good whose demand increases when income increases and falls when income falls.

When income increases, the demand for desk lamps would increase if they are normal goods.

An inferior good is a good whose demand increases when income falls and whose demand falls when income rises.

The demand for desk lamps would fall when income rises if desk lamps are inferior goods.

A subsituite good is a good that can be used in place of another good. If floor lamps are a substitute for desk lamps and the price of floor lamps increases, consumers would reduce their demand for floor lamps and increases their demand for desk lamps.

Complementary goods are goods that are used together. If desks and desk lamps are complementary goods, a decrease in the price of desk would lead to an increase in the demand for desk lamps when an increase in the price of desk would lead to a decrease in the demand for desk lamps.

I hope my answer helps you

the answer would be voluntary exchange -

"the act of buyers and sellers freely and willingly engaging in market transactions. moreover, transactions are made in such a way that both the buyer and the seller are better off after the exchange than before it occurred."
