单选题 Amidst the second worst recession in United States history, thrifty consumers are turning to the internet to take advantage of special offers.
Emily, a California school teacher and full time mother, is one such consumer. It all staned about three months ago when she bought an authentic Coach pocketbook on sale for only $ 55 (75% off the retail price). She was determined to seek out other great offers and recently made her best find. Emily discovered a clever way of combining two different teeth whitening offers from two different companies - Dazzle White and Total White - to get results similar to that of a Drofessional whitening done by a dentist. Rather then spending $ 500 at her local dentist to attain a perfect smile, she was able to do so for less than $ 5 by using free trial * offers she found online.
Who did Emily do for a job?

• A. She was a school teacher.
• B. She was a housewife.
• C. She was the sales representative of Dazzle White.
• D. She was an online advertising designer.
