Step 1: Reye syndrome is an acute, non inflammatory encephalopathy with fatty change in the liver. It damages many organs, especially the brain and liver, and characteristically causes low blood sugar (hypoglycaemia) and a raised ammonia level. So hypoglycaemia (option d) is a true feature.
Step 2: It typically follows a viral illness such as influenza or varicella, classically when salicylates (aspirin) have been given. This confirms that salicylate ingestion (option a) is a true association. The fatty infiltration enlarges the liver, so hepatomegaly (option b) is also true.
Step 3: The liver shows fatty change with minimal inflammation, and liver enzymes rise while bilirubin stays normal. Because bilirubin is not elevated, jaundice is usually absent. Therefore the false statement is jaundice, making option c the answer.
