Which of the following options are correct ........??????????
Dear Student,
A nucleus which has lower n/p ratio , is placed below the belt of stability either emits positrons or undergoes electron capture. Both modes of decay decrease the number of protons and increase the number of neutrons in the nucleus and thus, positron emission or electron capture results in an increase in n/p ratio.

Heavy nuclei show K - electron capture in preference to positron emission, therefore correct answer is (iv)
