[单选题]Text 3 Drones,originally developed for military purposes,weren't approved for commercial use in the United States until 2013.When that happened,it was immediately clear that they could be hugely useful to a whole host of industries-and almost as quickly,it became clear that regulation would be a problem.The new technology raised multiple safety and security issues,there was no consensus on who should write rules to mitigate those concems,and the knowledge needed to develop the rules didn't yet exist in many cases.In addition,the little flying robots made a lot of people nervous.Such regulatory,logistical,and social barriers to adopting novel products and services are very common.In fact,technology routinely surpasses society's ability to deal with it.That's partly because tech entrepreneurs are often insouciant about the legal and social issues their innovations birth.Although electric cars are subsidized by the federal govemment,Tesla has run afoul of state and local regulations because it bypasses conventional dealers to sell directly to consumers.Facebook is only now facing up to major regulatory concerns about its use of data,despite being massively successful with users and advertisers.It's clear that even as innovations bring unprecedented comfort and convenience,they also threaten old ways of regulating industries,running a business,and making a living.This has always been true.Thus early cars weren't allowed to go faster than horses,and some 19th-century textile workers used sledgehammers to attack the industrial machinery they feared would displace them.New technology can even upend social norms:Consider how dating apps have transformed the way people meet.Interestingly,the same institutional disorder that pervades nascent industries such as drones and driverless cars is something I've also seen in developing countries.And strange though this may sound,I believe that tech entrepreneurs can leam a lot from business people who have succeeded in the world's emerging markets.Entrepreneurs in Brazil or Nigeria know that it's pointless to wait for the govemment to provide the institutional and market infrastructure their businesses need,because that will simply take too long.They themselves must build support structures to compensate for what Krishna Palepu and I have referred to in earlier writrngs as"institutional voids."They must create the conditions that will allow them to create successful products or services.
Which of the following is true about drones?
A.It is under proper supervision.
B.It has multiple purposes.
C.It is opposed by people.
D.It has no security problem.
