A) is correct because in Hadoop's HDFS architecture, the DataNode is indeed the slave or worker node that stores the actual data in blocks. The NameNode, in contrast, manages the file system namespace and metadata, not the data itself. The default block size in HDFS is 128 MB (not 32 MB as stated in option B), making B incorrect. C is incorrect because the NameNode does not store user data in data blocks; it stores metadata.
