A Correct answer
Explanation

A trap, also known as a software interrupt, is synchronous because it is triggered directly by the execution of a user instruction (such as a system call or error like division by zero). Asynchronous interrupts are typically generated by external hardware events independent of the CPU instruction cycle.
