The Correct Option is B
Solution and Explanation
Step 1: Measles (rubeola) is a highly communicable acute viral disease marked by prodromal fever, cough, coryza and conjunctivitis, with pathognomonic Koplik spots, followed by an erythematous maculopapular rash on the third to seventh day.
Step 2: The generalised immunosuppression that follows acute measles often predisposes to bacterial otitis media and bronchopneumonia. These are common, but not the most serious.
Step 3: In about 0.1% of cases measles causes acute meningo-encephalitis, which is the most serious acute complication. Subacute sclerosing panencephalitis (SSPE) is a rare chronic degenerative disease appearing years later.
Conclusion: Among the listed options, meningo-encephalitis is the most serious complication.
