Helm serves as a package manager for Kubernetes applications, streamlining the deployment and management of applications on Kubernetes clusters. It helps users define, install, and upgrade even the most complex Kubernetes applications through "charts," which are pre-configured packages of resources. This abstraction makes it much easier to manage the various components that an application requires, like deployments, services, and configuration maps, all defined in a single, reusable Helm chart.

Using Helm, developers and operators can manage application versions, rollbacks, and dependencies efficiently, allowing for consistent and repeatable application deployments across different environments. This functionality is crucial in a Kubernetes ecosystem where applications are often composed of multiple microservices and can significantly enhance productivity and consistency.

The other options, while relevant to Kubernetes in their own right, do not describe the purpose of Helm. A container runtime is responsible for running containers, a security tool focuses on access management, and a monitoring solution is dedicated to observing cluster health and performance metrics. Helm stands apart from these functionalities as a comprehensive package management tool specifically designed for Kubernetes environments.
