单选题Why has public opinion regarding drunken driving changed?A Detailed statistics are now available.B The news media have revealed the problem.C Judges are giving more severe sentences.D Drivers are more conscious of their image.

Drunken driving, sometimes called America's socially accepted form of murder, has become a national epidemic. Every hour of every day about three Americans on average are killed hy
drunken drivers, adding up an incredible 350,000 over the past decade.
A drunken driver is usually defined as one with a 0.10 blood alcohol content or roughly three beers, glasses of wine or shots of whisky drunk within two hours. Heavy drinking used to be an acceptable part of the American alcohol image and judges were lenient in most courts, but the drunken slaughter has recently caused so many well-publicized tragedies, especially involving young children, that public opinion is no longer so tolerant.
Twenty states have raised the legal drinking age to 21, reversing a trend in the 1960s to reduce it to 18. After New Jersey lowered it to 18, the number of people killed by 18 to 20-year-old drivers more than doubled, so the state recently upped it back to 21.Reformers, however, fear raising the drinking age will have little effect unless accompanied by educational programs to help young people to develop"responsible attitudes" about drinking and teach them to resist peer pressure to drink.
Tough new laws have led to increased arrests and in many areas already, to a marked decline in fatalities. Some states are also penalizing bars for serving customers too many drinks.
As the fatalities continue to occur daily in every state, some Americans are even beginning to speak well of the 13 years' national prohibition of alcohol that began in 1919, which President Hoover called the"noble experiment". They forget that legal prohibition didn't stop drinking, but encouraged political corruption and organized crime. As with the booming drug trade generally, there is no easy solution.
The rule that only people above 21 years of age can drink__________.

A.is a new law promoted by the twenty states
B.had been once adopted before the 1960s
C.has been enforced since the prohibition of alcohol
D.will be carried out all over the country
