Assertion :
Severe Acute Respiratory Syndrome (SARS) originated in China.
Reason: China is the most populated country of the world.The world health organization (WHO) reported China as the origin place of SARS. Several other countries have reported SARS cases after travel to China and its nearby areas/countries in Asia or close contact with a person affected with SARS. Microbiologists of Hongkong Central University initially detected a virus metapneumovirus and identified as corona virus causative agent of SARS. It is very known fact that the China is the most populated country. This fact cannot be correlated with SARS. So, the correct answer is 'Both Assertion and Reason are correct but Reason is not the correct explanation for Assertion'.
