(a) so as to jump to some other location where there is a wider space of memory available to write the codes
(b) so as to avoid overwriting of other interrupt instructions
(c) all of the mentioned
(d) none of the mentioned

My doubt stems from Interrupt Programming topic in section 8051 Microcontroller of Microcontroller
