Which Azure feature provides security recommendations for Azure App Service web apps and Azure Functions?

Compute & apps in Azure Security Center is the correct answer because Azure Security Center (now Microsoft Defender for Cloud) provides unified security management and advanced threat protection across your hybrid cloud workloads. Specifically, its "Compute & apps" section offers security recommendations tailored for Azure App Service web apps and Azure Functions, identifying vulnerabilities and suggesting remediation steps. Security & Compliance in Azure Log Analytics is incorrect because Log Analytics is primarily for collecting and analyzing log data, not for providing security recommendations. Resource health in Azure Service Health is incorrect as it focuses on the health status of Azure services and resources, not security recommendations. Smart Detection in Azure Application Insights is incorrect because it automatically detects performance anomalies and failures in your applications, not security vulnerabilities.
