Answer :
I believe the answer is: All needed services cannot be adequately provided by businesses.
Example of this are products that considered to be basic necessities such as clean water. If we give the control of clean water to the corporation, they could rise the product as high as they like and the consumers have no choice but to accept it, since we would die without the product
for plato, the answer is d. all needed services cannot be adequately provided by businesses!!
