BlivenessProbe: httpGet: path: /healthz port: 8080 initialDelaySeconds: 10 periodSeconds: 5

ClivenessProbe: exec: command: ["curl", "-H", "X-Health:true", "/healthz"] initialDelaySeconds: 10 periodSeconds: 5

livenessProbe: httpGet: path: /healthz port: 8080 httpHeaders: - name: X-Health value: "true" initialDelaySeconds: 10 periodSeconds: 5 correctly uses httpHeaders with name and value fields under httpGet.
Final Answer:
Correct HTTP liveness probe with custom header -> Option D
Quick Check:
