Solution

The correct option is B

2


Since, noble gases have stable elecetronic configuration, thats their octet or duplet(in case of helium) of electrons is complete.

Therefore,2 is the electronic configuration of Helium which is a noble gas.

Atomic number of helium = 2

Therefore number of electrons = 2

Therefore, electronic configuration of helium is 2.(K shell)
