UEFI is a specification that defines a software interface between an OS and platform firmware. Where does this interface store information about files present on a disk?

The correct answer is B. GUID Partition Table (GPT). UEFI uses the GUID Partition Table (GPT) to store information about partitions and files on a disk. GPT replaced the older Master Boot Record (MBR) partitioning scheme and supports larger disks (beyond 2 TB), more partitions, and includes redundancy features like a backup…

Explanation

UEFI uses the GUID Partition Table (GPT) to store information about partitions and files on a disk. GPT replaced the older Master Boot Record (MBR) partitioning scheme and supports larger disks (beyond 2 TB), more partitions, and includes redundancy features like a backup partition table at the end of the disk. The BIOS-MBR and MBR are associated with legacy BIOS systems, not UEFI. The BIOS Parameter Block is a data structure within the boot sector of a volume, not the UEFI partition information store.
