C. resembles in IVA (carbon family( since both have a half filled shell of electron
D. all correct.

Answer

D

Explanation

`HCIrarrH` has + oxidation state so it sesemble I A group property
`NaH rarr` H has -1 oxidation state so it resemble VII A group property
`H(1s^(1))` due to half filled shell of electron it resemble IV A group property
