Which protocol supports multi-master configuration?
(i) UART
(ii) I2C
(iii) RS232
(iv) SPI

Worked SolutionAI Assisted

Answer: (ii) I2C

Explanation: I2C supports multi-master arbitration and multi-slave. Any master can initiate transfer, bus arbitration handles collisions. UART/RS232 are point-to-point, SPI is single-master (in basic form, multi-master complex). Thus I2C is correct.
