I got this question by my school principal while I was bunking the class.

Question is from Exceptions topic in chapter Input/Output Organisation of Computer Architecture

Answer 1

Right option is (b) The instruction is halted and the exception is handled

For explanation I would say: Since the interrupt was raised during the execution of the instruction, the instruction cannot be executed and the exception is served immediately.
