Which file system has 32 bits assigned to the address clusters of the allocation table?
The correct answer is A. FAT32. FAT32 is named for its use of 32-bit entries in the File Allocation Table to address cluster locations on the disk.

Why each option
FAT32 is named for its use of 32-bit entries in the File Allocation Table to address cluster locations on the disk.
FAT32 (File Allocation Table 32) uses 32-bit values to store cluster addresses in the allocation table, which allows it to support larger volumes and more clusters than its predecessors. The '32' in the name directly refers to this 32-bit cluster addressing scheme, enabling partition sizes up to 2 TB and individual file sizes up to 4 GB minus 1 byte.
NTFS (New Technology File System) uses a Master File Table (MFT) rather than a File Allocation Table, and does not use the FAT addressing model at all.
EXT4 is a Linux journaling file system that uses inode-based addressing with extents, not a File Allocation Table with fixed-width cluster address entries.
FAT16 uses 16-bit entries in its allocation table, which limits it to a maximum of 65,536 clusters and much smaller partition sizes than FAT32.
