Which of the following statements about file system blocks is incorrect?

The statement that each file system block corresponds to a discontinuous area on the physical disk is incorrect because file system blocks are typically designed to represent contiguous areas of data on the disk. In a standard file system, a file is stored as a series of blocks that are ideally stored together in a sequential manner to optimize read and write operations. When blocks are organized contiguously, it allows for more efficient access times and reduces fragmentation.

The other options outline correct information about how file system blocks operate within a file system's architecture and how they interact with logical volume management (LVM). Specifically, the mention of the file being stored in the file system and the mapping to file system blocks accurately reflects how data is organized. The statement about file system blocks corresponding to logical areas in LVM is also true, highlighting the abstraction layer LVM provides between physical storage and logical storage. Finally, the assertion that the logical area is mapped to the physical area through LVM emphasizes how logical volumes provide flexibility in managing disk space, allowing users to allocate and use storage independently of the underlying physical layout.
