as we hear about osa fragments ! they are like steel balls !
like shotgun firing !
so number 2 is better answer but here is same question !

with miss distance 5 meter ... target could be kill with explosion wave ?
so from 5 meters + explosion wave + some of balls fragments ! kill percent going to high level !

this is easy question but for me hard to say

PS: Epap@ OSA warhead have how many of explosion degrees ?
this question could be help us to say true answer !!!!
