Interrupts are treated by Arm processors as a type of exception and are processed with the Exception Handler in the Nested Vectored Interrupt Controller (NVIC).

In assessing the statement, we start by identifying the core claim about how ARM processors treat interrupts. 
Option 1: True. The statement aligns with ARM architecture fundamentals, since interrupts are indeed a form of exception in ARM CPUs, and they are managed via the Nested Vectored Interrupt Controller (NVIC). The NVIC provides exception entry/exit handling, prioritization, and routing to the appropriate exception handlers, which is the typical workflow for interrupts on ARM Cortex-M devices. 
Option 2: False. If one were to select this, it would imply that interrupts are not considered exceptions or are managed outside the NVIC. However, that contradicts the standard ARM design where interrupts are implemented as exceptions and are handled through the NVIC’s exception mechanisms and vector table, including the processor entering an exception state and jumping to the relevant handler. 
To further differentiate, recall that an ARM exception model includes reset, NMI, hard fault, and various interrupt exceptions; all of these pass through the exception mechanism and are mapped to handlers via the NVIC’s vector table and priority logic. The NVIC is specifically designed to manage nested interrupts, control preemption, and provide baseline hardware support for interrupt prioritization, preemption, and tail-chaining where applicable. 
Therefore, the statement reflects the established architecture where interrupts are treated as exceptions and are processed by the NVIC through the exception handler pathways. 
In summary, the key points are: interrupts are exceptions in ARM terminology, and the NVIC is the hardware unit responsible for routing to the correct handler and managing interrupt priorities and nesting.
