C. I, II, III
Explanation:
In a period of falling interest rates, a bond dealer would engage in all of the following activities except for IV. Therefore, a dealer would raise his quoted price in Bloomberg. If the dealer has an appreciated bond that he wishes to sell, he can place ''Request for Bids'' for those bonds in Bloomberg. The dealer may buy bond the he has previously sold short to limit losses due to rising price. To protect existing short position against the rising price, the dealer will buy call options, not put options. Put options are used in protecting existing long position from falling price.
