(C) SARS Cov-3
(D) None of these
🧠 Explanation:
The World Health Organization officially named the virus that causes COVID-19 as **SARS-CoV-2** (Severe Acute Respiratory Syndrome Coronavirus 2). This name reflects its genetic similarity to the virus responsible for the 2003 SARS outbreak. SARS-CoV-2 is a type of coronavirus, characterized by its crown-like spikes on the surface. The name was chosen to provide a clear scientific reference and avoid geographic or cultural bias. In grammar, “SARS-CoV-2” is a **proper noun** representing a specific virus. Alternatives in casual contexts could be “novel coronavirus” or “COVID-19 virus,” though the latter refers to the disease rather than the pathogen.
