took test

The answer to the question is (B) necessary capital.

This is because what consumers want is what consumers will inevitably buy, and when consumers buy products, it would give revenue to the producers of the goods.

If the producers manufacture goods that the consumers do not have any interest in buying, it would lead to a loss in revenue and profit. Thus, since the capital is generated from the consumers, producers should strive to generate profit based on this.
