It can form bonds in $+1$ as well as $-1$ oxidation state.

(A) Hydrogen exhibits a $+1$ oxidation state by losing its electron (e.g.,in $HCl$) and a $-1$ oxidation state by gaining an electron (e.g.,in $NaH$). Thus,it can form bonds in both $+1$ and $-1$ oxidation states. Therefore,the correct option is $A$.
