Answer:
a - Hydrogen has the same monovalent electropositive valency as the alkali metals (1+). This is because of its ability to donate one electron to attain stability.
b - Hydrogen and alkali metals both can act as reducing agents. As Hydrogen can donate electrons, like alkali metals, they have a low value of ionisation energy and can donate electrons easily
