(A) Hydrogen $(H)$ has the electronic configuration $1s^1$. By accepting one electron,it achieves the stable configuration of Helium $(He)$,which is $1s^2$.$H + e^- 	o H^- (1s^2)$Similarly,halogens (Group $17$ elements) have a valence shell configuration of $ns^2 np^5$. By accepting one electron,they achieve the stable noble gas configuration $(ns^2 np^6)$.$F + e^- 	o F^- ([He] 2s^2 2p^6)$Therefore,hydrogen resembles halogens in its ability to gain an electron to complete its shell.

Hydrogen accepts an electron to form an inert gas configuration. In this property,it resembles:
