Answer:
Bronsted-Lowry acid
Explanation:
Bronsted-Lowry Base -
According to Bronsted-Lowry theory of acids and bases:
Acids are those substances which donate proton in the solution whereas bases are those substances which accept proton in the solution.
Consider an example,
[tex]HCO_3^{-} + HOH\; \rightarrow H_2CO_3 + OH^{-}\\[/tex]
HCO3- behave as base as it accepts proton in the reaction whereas HOH behaves as acid as it releases proton.
According to Lewis theory of acids and bases:
Acids are electron acceptor and bases are electron donar. Acids are generally electron deficient species whereas Lewis are chemical species having lone pair of electrons.
For example, AlCl3 is behave as Lewis acid because of being electron deficient species.
NH3 is a Lewis base because of presence of lone pair of electrons.
Therefore, among given options, Bronsted-Lowry acid is the correct option.
