The sentence states that these cultural groups "know very little of the true causes" and therefore it is unlikely that they developed vaccinations or immunizations (A) which require understanding of germ theory. Similarly, laws and codes (C) would require a level of understanding and organization that may not have been present in some cultural groups. Mechanical tools and safety devices (D) may have been developed, but the sentence specifically refers to protection from disease and illness which is unlikely to be prevented solely by mechanical tools. This leaves choice (B) as the most likely option, as cultural groups most likely developed various practices (such as keeping infants isolated or using specific herbs) to protect their infants from illness, even if they didn't fully understand the causes.
