• B. Amazon EMR ✓
• C. AWS Lambda
• D. Amazon Redshift

Correct Answer: B. Amazon EMR

Explanation

题目中公司需要迁移本地工作负载到AWS并减少运营开销，还想探索无服务器选项，同时当前工作负载使用多种技术且能在几秒内处理PB级数据，迁移后需保持类似或更好性能。AWSGlue主要用于数据发现和ETL工作流的编排；AWSLambda是无服务器计算服务，不太适用于大规模数据处理；AmazonRedshift是数据仓库服务。而AmazonEMR支持ApachePig、Oozie、Spark、HBase和Flink等技术，适用于大规模数据处理，能够满足公司在几秒内处理PB级数据的要求，并降低运营开销。所以答案是B。
