The Federal Reserve (the Fed) controls the money supply by deliberately creating and destroying money. When we talk about "creation of money", what do we mean? a. The Fed collects old/used coins and dollar bills, takes them out of circulation, and replaces them with new ones in a higher quantity. b. The Fed orders private banks to extend more loans to people (such as mortgages), and this ends up creating money. c. The Fed prints money, then it uses those newly printed dollars to buy bonds and so puts the new money into circulation. d. The Fed edits its computer database to increase the number of dollars in it, then it uses those extra digital dollars to buy bonds and so puts the new money into circulation
