GPT is a partition table format for hard disks and UEFI is a pc firmware on a chip on the motherboard. How can be this the same? I also think A and B is correct.
About the D: what do you mean with "within" exactly?
Of course the firmware is not stored inside GPT, but has inside/within link to interpret the partitions table, exactly, GPT should be in our primary physical drive storage, EFI on /boot.
UEFI is not stored in GPT metadata. They are separate entities, with UEFI residing in firmware on the motherboard and GPT metadata residing on the storage device in the EFI System Partition.
Option A: It can read and interpret partition tables
UEFI firmware is responsible for initializing the hardware and loading the operating system. This includes reading and interpreting the partition table on the boot drive. The partition table tells the firmware where the operating system is located and how it is partitioned.
Option B: It can use and read certain file systems
UEFI firmware can only read certain file systems, such as FAT and NTFS. It cannot read or write to Linux file systems, such as ext4 and XFS.
B and D are correct.

GPT-partitioned disks can be used either with computers with the traditional PC BIOS or ones with UEFI firmware. On machines with a BIOS, the second part of GRUB is stored in a special BIOS boot partition.
On systems with UEFI firmware, GRUB is loaded by the firmware from the files grubia32.efi (for 32-Bit systems) or grubx64.efi (for 64-Bit systems) from a partition called the ESP (EFI System Partition).
"GRUB is loaded by the firmware [...] from a partition called the ESP (EFI System Partition)."
GRUB is loaded by the (UEFI) firmware in order to boot the OS.
The UEFI firmware itself is located in a chip on the motherboard, and is not loaded from the GPT metadata (which is located on the hard drive).
Therefore, A & B are the correct answers, and not B & D.
Actually D seem to be correct: (Quoting https://wiki.restarters.net/UEFI_and_GPT )
"In order to work with UEFI, one of the partitions on a GPT disk must be a special system partition known as the ESP (EFI System Partition). UEFI can recognise this, understand a FAT file system on it, and find the files on it required for booting the computer."
