Toxic bioaccumulation, a mining hazard induced by the mercury compounds transferred from unrefined cinnabar ore, presently afflicts 7 of every 10 workers in the Redstone Mine. A second mineral which occurs in the same environment, chalcedony, restricts the release of toxins from cinnabar ore. Mining chemists suggest spreading chalcedony in the Redstone Mine in order to preserve the surviving workers.

Which of the following, if true about chalcedony, provides the strongest evidence that the suggestion will be successful?

A It accumulates in deposits which are concentrated in the mineral veins where cinnabar is found.

B It can on some occasions stay inactive in mineral veins for almost five years before it begins to spread.

C It spreads through an environment more gradually than does cinnabar in most geological settings.

D It does not prevent a few common varieties of cinnabar ore from releasing toxins.

E It can occasionally damage fish populations by poisoning their gills.

Answer must be (A) for the highlighted errors in other options....

(B) Suggests Inactivity of the mineral , which is out of context.
(C) Spreading of minerals , not relevant and useful under the current context.
(D) Releasing toxins (Some variety) restricts the cope..
(E) Damaging fish population is out of scope..
