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：all of any given pollutant that is to be controlled actually reaches the North Sea at present
根是否到达没有关系，有些污染并没有到达但依然是污染。现在没有到达不代表将来也不会到达
