Point out the correct statement.

The correct answer is A. HDF5 is a hierarchical format.

HDF5 (Hierarchical Data Format, version 5) is a data format and software library for storing and managing large amounts of data. It is a hierarchical format, meaning that data is stored in a tree-like structure.

This makes it easy to organize and access data. HDF5 supports a wide range of data types, including integers, floating-point numbers, strings, and arrays. It is also a very efficient format, making it ideal for storing and managing large datasets.

Option B is incorrect because HDF5 does support a range of different data types.

Option C is incorrect because HDF5 is not used for storing small datasets. It is a very efficient format, making it ideal for storing and managing large datasets.

Option D is incorrect because A is the correct answer.
