The command to check the current resource usage statistics of Pods in a Kubernetes cluster is 'kubectl top'. This command retrieves and displays metrics such as CPU and memory usage directly from the Metrics Server, which gathers this data from the kubelet running on each node.

Utilizing 'kubectl top' allows developers and operators to quickly assess the resource consumption of individual Pods, enabling them to monitor the health and performance of their applications effectively. This is essential for identifying potential bottlenecks, ensuring that resource allocation is appropriate, and facilitating efficient scaling decisions.

In contrast, the other options listed do not correspond to valid Kubernetes commands for checking resource usage. For instance, 'kubectl check stats', 'kubectl stats', and 'kubectl get usage' are not recognized commands within the Kubernetes CLI, hence they would not yield the desired information regarding Pod resources. Therefore, 'kubectl top' is the correct and effective choice for obtaining current resource usage statistics of Pods in a Kubernetes environment.
