Correct option is A

Sol. SARS stands for Severe Acute Respiratory Syndrome, a viral respiratory illness caused by a coronavirus. Explanation of each option:
· (a) Severe Acute Respiratory Syndrome – Correct. SARS stands for Severe Acute Respiratory Syndrome, a serious respiratory illness caused by a virus (SARS-CoV). It was first identified in 2002-2003 and caused a global outbreak, characterized by fever, cough, and difficulty breathing.
· (b) Standard Acute Respiratory Syndrome – Incorrect. Standard Acute Respiratory Syndrome is not a real medical condition. The correct term is Severe Acute Respiratory Syndrome (SARS), not "standard."
· (c) Severe Acute Respiratory Symptoms – Incorrect. Severe Acute Respiratory Symptoms is a descriptive phrase, but it does not correspond to the acronym SARS. The term does not accurately represent the condition or the medical term.
· (d) Sub Acute Respiratory Syndrome – Incorrect. Sub Acute Respiratory Syndrome is not a recognized medical term. The correct term is Severe Acute Respiratory Syndrome, and "sub acute" does not describe the severity level associated with SARS.
