D Correct answer
Explanation

Hydrogen can gain one electron to achieve the stable helium configuration (1s²), which is characteristic of halogens (Group 17 elements) that need one electron to complete their octet. This is why hydrogen is placed above fluorine in some periodic tables, showing 'halogen-like' behavior. Alkali metals lose electrons, inert gases already have stable configurations, and alkaline earth metals lose two electrons.
