Clearly, fitness consultants who smoke cigarettes cannot help their clients become healthier. If they do not care about their own health, they cannot really care for their clients' health, and if they do not care for their clients' health, they cannot help them to become healthier. The conclusion follows logically if which one of the following is assumed? ['Anyone who does not care for his or her own health cannot help others become healthier.', 'Anyone who cares about his or her own health does not smoke.', 'Anyone who cares about the health of others can help others become healthier.', 'Anyone who does not care for the health of others cannot help them become healthier.']
