Show answer & explanation
Correct answer: B
In a vectored interrupt, the hardware mechanism automatically determines the address of the Interrupt Service Routine (ISR). The interrupting device directly provides this branch information to the processor, allowing it to jump immediately to the correct handler without needing a software poll or lookup table.
