Best answer
Right option is (a) To turn off interrupt

Easy explanation: The interrupt service routine can be used to automate a number of functions in an arduino. In a situation where the entire focus of the code is bound to one function, the ISR can act as a pause for the arduino to stop the current function temporarily and divert memory to another function. The detachInterrupt() function turns off the ISR functionality temporarily.
