You will monitor a multi-tier application (App1) deployed across containers in Azure Container Instances. The monitoring solution must provide synthetic transaction monitoring between application components and require minimal development effort. Which Azure Monitor capability should you include?

Application Insights is the correct choice because it provides comprehensive Application Performance Management (APM) for live web applications, including synthetic transaction monitoring. It can automatically detect performance anomalies, diagnose issues, and track usage patterns. This capability directly addresses the requirement for synthetic transaction monitoring between application components with minimal development effort, as it can be integrated with little to no code changes for many application types. Network insights focuses on network health and connectivity, not application-level transaction monitoring. Container insights monitors the performance of containers and Kubernetes clusters, but not the synthetic transactions between application components. Log Analytics Workspace insights provides monitoring solutions for various Azure resources, but it's a general-purpose logging and analytics service, not specialized for synthetic transaction monitoring of applications like Application Insights.
