Explanation
Option B is correct because the statement contains a factual error: Huawei Cloud MRS builds big data clusters based on virtual machines (ECS instances), not containers. While MRS does deploy and manage Hadoop ecosystems on Huawei Cloud and does support one-click cluster deployment, the claim about container-based infrastructure is inaccurate.
Option A is wrong because it accepts the flawed premise that MRS uses containers as its underlying compute layer, which misidentifies the architecture of the service.
Memory tip: Associate containers with Huawei's CCE (Cloud Container Engine), and remember that MRS relies on ECS (Elastic Cloud Server) virtual machines - "MapReduce runs on machines, not containers."
