Correct option is B

Sol. SARS (Severe Acute Respiratory Syndrome) is a viral respiratory illness caused by SARS-CoV, first identified in 2003. It causes fever, dry cough, and breathing difficulty. It is closely related to SARS-CoV-2, the virus responsible for COVID-19.
Explanation of each option:
· (a) Standard Acute Respiratory Syndrome – Not a valid medical term; no such syndrome exists.
· (b) Severe Acute Respiratory Syndrome – Correct. Recognized disease caused by a coronavirus, known for its epidemic in 2003.
· (c) Sub-Acute Respiratory Syndrome – Sub-acute implies gradual onset; SARS is acute and severe.
· (d) Showing All Respiratory Symptoms – Not an official expansion; seems like a casual phrase.
