Answer:
d. The business's number of products
Explanation:
The lack of ethics in a firm does not necessarily affect the number of products it makes. In fact, it could actually enhace the output.
For example, if a large manufacturer decides to employ child labor in a developing country, it could see its output skyrocket without incurring in significant costs, but the action in itself is highly unethical, and if it was found out, it would affect the company's image, customers, and suppliers.
