Explanation:

Coronaviruses are a specific family of viruses, with some of them causing less-severe damage, such as the common cold, and others causing respiratory and intestinal diseases. A coronavirus has many “regularly arranged” protrusions on its surface, because of which the entire virus particle looks like an emperor’s crown, hence the name “coronavirus”. Apart from human beings, coronaviruses can affect mammals including pigs, cattle, cats, dogs, martens, camels, hedgehogs and some birds. So far, there are four known disease-causing coronaviruses, among which the best known are the SARS corona virus and the Middle East Respiratory Syndrome (MERS) coronavirus, both of which can cause severe respiratory diseases. In the newly identified coronavirus, a direct link with the disease has not been established yet.The death toll from the coronavirus has risen to 17 in Wuhan, China, with several cases reported across the country. US has also reported a case of the virus, raising concerns across the world.Hence only 2nd is correct.
