- It includes peripherals devices on a single chip with a hard disk, processor, and input/output (I/O).
- Most of the electronic devices are powered by embedded microcontroller circuitry that incorporates sensors with processor circuits.
No other alternative to power these devices by built-in circuits. So, the correct answer is Alternative A.
