(单选题)16: In an Indianapolis neighborhood where some teenage girls flaunt pregnancies like new hairdos, Aisha Fields is unabashedly square: She plans to abstain from sex until she marries. "Most of my friends already have babies," says Aisha, a high school junior and abstinence mentor. "Being pregnant is a fashion. Girls go around bragging:‘I'm three months (pregnant).' They think it's cool." With 1 million US teens becoming pregnant every year, and 13 percent of all American babies born to teens, Aisha's "just-say-no" attitude is a policymaker's dream come true. Federal and state officials are banking on such an attitude as they launch a new campaign to shrink the ranks of unwed teenage moms. On Oct. 1, the government will begin dispensing some of the nearly $850 million earmarked under the welfare—reform law over five years for teaching abstinence and preventing out-of-wedlock births. But experts say there is no research to suggest that abstinence—only education will succeed. In contrast, more comprehensive programs that cover contraception, family planning, and communication skills can help delay sexual involvement by teens, according to a study by the National Campaign to Prevent Pregnancy in Washington. "It seems foolish to be tossing away all this money without knowing whether it will work," says Lisa Kaeser, a senior associate at the Alan Guttmacher Institute, a Washington-based nonprofit group that researches reproductive health. But experts agree the latest campaign against teen pregnancy marks a big improvement over older policies in one fundamental respect: It emphasizes prevention. Question:Aisha Fields ____________.

A: is pregnant

B: is planning to marry

C: decides not to become pregnant before marriage

D: is unabashed
