Correct Answer

Explanation

The AVR microcontroller is an 8-bit RISC architecture that was developed by Atmel. It follows the Harvard architecture, which separates instruction and data memories. Zilog80, 8051, and Motorola 6800, on the other hand, are examples of microcontrollers with CISC (complex instruction set computing) architectures.
