Answer:
From the above given option, metadata in Hadoop is stored by option b) Name node.
Hadoop uses Hadoop distributed file system for data storage. This file system can be classified into two types of components. One is Datanode and the other is Namenode.
Data node is regarded as the slave node which stores the actual original data.
Namenode is regarded as the master node in which metadata like size of the block , permission of the file , location of the data are stored.
