Solution

The correct option is B neon
Electronic configuration of carbon with atomic no. 6 = 2,4
The four valence electrons are involved in bonding with the four hydrogen atoms. Therefore after formation of four covalent bonds with hydrogen, atomic number of carbon in $C H_{4}$ is 2+4+4 = 10, which is same as that of neon.
Option B is correct.
