On a UEFI-based system, which of the following invokes GRUB2 from the EFI command prompt?
The correct answer is C. /boot/EFI/grub2.efi. On UEFI-based systems, the EFI System Partition (ESP) is typically mounted at /boot/EFI (or /boot/efi).

Explanation
On UEFI-based systems, the EFI System Partition (ESP) is typically mounted at /boot/EFI (or /boot/efi). GRUB2's EFI binary is stored under that mount point, making the full path /boot/EFI/grub2.efi (or a vendor-specific subdirectory thereof). This is the path used to invoke GRUB2 from the UEFI/EFI shell. Option A uses an invalid syntax (boot//EFI/), option B is a relative path (missing the leading /boot), and option D places the binary at the filesystem root, which does not reflect standard EFI partition layout.
