How is the accuracy of the oxygen determination affected by the addition of a gas into the stream that is reduced by a reaction analogous to that of oxygen?

A) Increased, because the smaller the amount of oxygen in the stream, the more effective is microanalysis

B) Increased, because the larger the sample reduced, the less effect a small variation in measurement will have on results

C) Decreased, because the partial pressure of oxygen will be decreased

D) Decreased, because the method cannot distinguish oxygen from the added gas
