[单项选择]

Age has its privileges in America, and one of the more prominent of them is the senior citizen discount. Anyone who has reached a certain age -- in some cases as low as 55 — is automatically entitled to a dazzling array of price reductions at nearly every level of commercial life. Eligibility is determined not by one’s need but by the date on one’s birth certificate. Practically unheard of a generation ago, the discounts have become a routine part of many businesses -- as common as color televisions in motel rooms and free coffee on airliners.
People with gray hair often are given the discounts without even asking for them; yet, millions of Americans above age 60 are healthy and solvent (有支付能力的). Businesses that would never dare offer discounts to college students or anyone under 30 freely offer them to older Americans. The practice is acceptable because of the widespread belief that "elderly" and "needy" are synonymous (同义的). Perhaps
A. offering senior citizens discounts has become routine commercial practice
B. senior citizen discounts have enabled many old people to live a decent life
C. giving senior citizens discounts has boosted the market for the elderly
D. senior citizens have to show their birth certificates to get a discount
