A

During a system boot cycle, after the BIOS (Basic Input/Output System) completes its tasks, the next program that is executed is the bootloader.

The bootloader is a small program that is responsible for loading the operating system kernel into memory. It is typically stored in the Master Boot Record (MBR) of the disk, which is the first sector of the disk. The bootloader is executed by the BIOS after it completes its initial hardware checks and system initialization.

Once the bootloader is executed, it loads the kernel into memory and passes control to it. The kernel is the core component of the operating system and is responsible for managing system resources, providing services to applications, and facilitating communication between hardware devices and software programs.

After the kernel is loaded into memory, the next program that is executed is the init program. The init program is responsible for starting system services and processes, initializing the system, and bringing the system to a usable state.

In summary, the correct answer to the question is A. The bootloader is executed after the BIOS completes its tasks during a system boot cycle.
