The false statement about interrupts is D

Trap is a hardware generated interrupt.

A trap is actually a software-generated interrupt or exception. Traps are typically triggered by instructions in a program, such as system calls or other exceptional conditions, rather than external hardware signals. Therefore, the statement that "Trap is a hardware generated interrupt" is false. Traps are part of the software mechanism for handling exceptional conditions.
