Explanation:

Bryan opposed the fixed - value gold standard and supported bimetallism which was a currency system based on two metals (gold and silver). The other options are incorrect as there is no evidence for career - based shifts, bimetallism doesn't call for a fixed value for gold in the way described in the second option, and there's no indication of different stances based on audience.

Answer:

Bryan opposed the idea of a fixed value for gold while supporting the concept of a currency based on two metals.
