Increases in antibiotic resistance, especially strains of antibiotic resistant tuberculosis, have contributed significantly to the reemergence of infectious diseases. This is due to over-prescription of antibiotics and the use of antibiotics in agriculture.

Reductions in vaccinations, often due to urban myths such as the false link between vaccines and autism or susperstitions about vaccines as a western plot in developing countries, have led to reemergence of diseases.

Global warming has increased the range of diseases such as West Nile and Malaria due to increasingly wide geographical ranges if insect vectors.

Lack of strong public health also contributes to disease spread.

Thus the answer isB, which is actually not true.
