As More of a Good, Such as Television Sets, Is

As more of a good, such as television sets, is produced, the opportunity cost of producing it increases. This most likely occurs because:

A) as more of a good is produced the inputs used to produce that good will increase in price
B) resources are not equally well- suited to producing all goods and as more of a good is produced it is necessary to use resources less well- suited to the production of the good
C) as more of a good is produced the quality of the technology available to produce additional units of the good declines and therefore the costs of production increase
D) consumers would be willing to pay higher prices for the good as more of the good is produced
