Which statement describes CNS symptoms that can occur in severe West Nile virus cases?

When West Nile virus reaches the central nervous system, it can cause meningitis and encephalitis. Signs of CNS involvement reflect irritation of the brain and meninges and disruption of neural function. Stiff neck is a classic sign of meningitis, while photophobia (light sensitivity) often accompanies meningeal irritation. Confusion indicates brain involvement or encephalitis. Tremors and numbness point to involvement of motor pathways and brain regions that control movement and sensation. So a description that includes numbness, tremors, light sensitivity, confusion, and a stiff neck captures the CNS effects seen in severe neuroinvasive West Nile disease. The other options describe symptoms that are not CNS-related or are typical of milder illness (headache and nausea alone) or unrelated conditions (cough and shortness of breath; trunk rash), which don’t reflect the CNS manifestations of severe West Nile infection.
