Recent evidence reported in leading medical journals suggests that hearing loss affects 75% of citizens over the age of 70. A state legislature, concerned with increasing the quality of care to its senior citizens, passes a bill providing that only medical doctors with specialized training in audiology may prescribe and sell hearing aids. The law provides a "grandfather clause" however, exempting all currently registered vendors of hearing aids who have no medical training, as long as they remain in business. A doctor who operates a hearing clinic, brings suit challenging the "grandfather clause" exemption in the new statute. Is the exemption in the law for all currently registered vendors of hearing aids constitutional? Group of answer choices Yes, because the classification between existing and new vendors has a rational basis. Yes, because those who lawfully engage in an occupation have a fundamental right to continue to do so. No, because the statute denies the equal protection of the laws to those patients who purchase hearing aids from non-physicians. No, because the statute denies non-physicians desiring to enter this occupation the equal protection of the laws
