What is a critic of recycling most likely to say? 

A)  Incineration is a very safe and efficient way to dispose of solid wastes. 
B)  Recycling is not worth the effort. 
C)  Recycling does not make sense if it costs more than landfilling or incinerating. 
D)  There is no solid-waste problem.

A critic of recycling is most likely to argue that it does not make economic sense if it costs more than other methods of waste disposal, such as landfilling or incineration. This is because they prioritize cost-effectiveness over environmental benefits. They may also argue that incineration is a safe and efficient alternative to recycling, which is reflected in choice A, but this is not necessarily the most common criticism of recycling. Choice B is a broad and unsupported statement that lacks any specific argument, while choice D is factually incorrect as solid waste is a well-established global issue.
