Ceteris paribus, an increase in the price of DVD players would tend to

A decrease the demand for DVD players.
B increase the price of televisions, a complement to DVD players.
C increase the demand for DVD players.
D increase the demand for VCRs, a substitute for DVD players.

To answer this question, we need to understand the concept of ceteris paribus (all other things being equal) and the relationship between the price of DVD players and the demand for DVD players.

Ceteris paribus assumes that all other factors that could affect the demand for DVD players remain constant. Therefore, we will focus solely on the relationship between the price of DVD players and the demand for DVD players.

An increase in the price of DVD players would tend to result in a decrease in demand for DVD players. This is because when the price of a product increases, consumers are less willing and able to purchase it. As a result, the quantity demanded decreases.

Hence, the correct answer is A - an increase in the price of DVD players would tend to decrease the demand for DVD players.
