Answer 2

Answer:

option a is correct

Explanation:

first of all you need to know what are isoelectronic species . so isoelectronic species are species or elements which have same number of electrons in them

so in first case sodium ion and neon are given.now sodium has 11 electrons but the + sign means it has lost one of its electrons now it means it is left with 10 electrons and on the other side Neon is a noble gases as you know it already and it has 10 electrons while in the other cases they don't have same number of electrons you can check and if you have any problem then you can ask again..
