Solution

The correct option is D 2,8,1
The atom belong to sodium , because the nuclear charge of the atom is 11 times and atomic mass of the atom is 23 ( nutron + protone) times of the hydrogen. As, hydrogen is having atomic mass and charge 1. Hence, the neutral sodium atom has 11 electrons and its its electronic configuration is 2,8,1.
