Which of the following best completes the passage below?
At a recent conference on environmental threats to the North Sea, most participating countries favored uniform controls on the quality of effluents, whether or not specific environmental damage could be attributed to a particular source of effluent. What must, of course, be shown, in order to avoid excessively restrictive controls, is that __________.
any uniform controls that are adopted are likely to be implemented without delay
any substance to be made subject to controls can actually cause environmental damage
the countries favoring uniform controls are those generating the largest quantities of effluents
all of any given pollutant that is to be controlled actually reaches the North Sea at present
environmental damage already inflicted on the North Sea is reversible
D：任何将被控制的污染物现在都污染了North Sea，说明这些污染物就应该被控制，不存在过度控制；
B：任何将被控制的物质可能实际上造成了污染，潜台词就是也可能没造成污染，那如果没造成污染的被控制了，就是过度控制。
