Answer:
Option a, [tex]H_2SO_4[/tex]
Explanation:
According to Arrhenius concept of acids and bases, acids are those substances which releases H+ in aqueous solution and bases are those which releases OH- in aqueous solution.
Among the given only [tex]H_2SO_4[/tex] can release [tex]H^+[/tex] in aqueous solution.
[tex]H_2SO_4 \rightarrow 2H^{+} + SO_4^{2-}[/tex]
LiOH releases [tex]OH^-[/tex], therefore it is an Arrhenius base.
[tex]NH_2CH_3[/tex] and [tex]CH_3CH_3[/tex] cannot releases [tex]H^+[/tex].
So, the correct option is option a.
