The correct answer is option 3 - China. In 2002, a new form of pneumonia named Severe Acute Respiratory Syndrome (SARS) originated in China. The outbreak was traced back to the province of Guangdong in southern China. The virus responsible for SARS is believed to have been transmitted from animals (most likely bats) to humans. From there, it spread within China and eventually to other countries through international travel. While there were cases of SARS reported in other countries, the initial outbreak and the majority of cases occurred in China. It is important to note that this information is based on scientific research and official reports, but there may still be ongoing investigations to fully understand the origins and transmission of the SARS virus.
