Answer:
C. 8,098 people worldwide became sick with Severe Acute Respiratory Syndrome (SARS) during the 2003 outbreak.
Explanation:
Parentheses in punctuation are used for clarification, explanation, translation, abbreviations, time intervals etc.
They are written after the term they clarify, so the option A. is incorrect.
Sentence will function just fine even if the part in brackets is left out, so the option D. is incorrect.
Besides parenthesis, there is no need for any other additional separations such as commas, so option B. is incorrect.
This leaves us with option C.
