Option 2 is incorrect as Floor Broker A floor broker is an employee in a securities or brokerage firm who executes orders on the floor for a stock

Option 3 is incorrect as Supplemental Liquidity Providers (SLPs) are market participants who create high volume on exchanges to increase liquidity in the markets by using high speed computers and algorithms. SLPs are generally  found in high liquid stocks with average daily trading volume of more than 1 million shares.
