A logical inconsistency related to market efficiency is as follows: If prices fully reflect available information, there is no motivation for investors to acquire information; hence, prices will not fully reflect available information. How is this logical inconsistency resolved? Select one: a. Moral hazard prevents market prices from being fully informative. b. Many investors stay out of the market because they do not view it as a "level playing field." C. Adverse selection in the market prevents market prices from fully reflecting available information. d. Noise or liquidity traders in the market make buy/sell decisions that are not based on a rational evaluation of relevant information. As a result, market prices are not fully informative
