Solution

The correct option is C
Small size of hydrogen atom and moderate electronegativity value of Hydrogen resembles as alkali metals

All alkali metals and Hydrogen have one electron in their valence shell and has the same valency. So, they have a moderate electronegativity and a smaller size because they have only one electron missing in the valence shell.
