Explanation / Answer

According to the Brønsted–Lowry theory, all acid– base reactions can be written as equilibria involving the acid and base and their conjugates.

PART (A): OPTION: 'D'

CN- will accept a proton from H2O becuase it does not have any proton to loose and H20 can donate a proton to it so CN- accepts a proton and act as a base and forms HCN which will act as an acid since it can donate the proton but it a conjugate acid to the base CN- .H2O will act as a base in this case since it is donating H+ to CN- .Afte donating a proton H2O will form OH- which is a base as it can accept a proton but it is a conjugate base to acid H2O   

PART (B): OPTION 'A'

H2PO4- is donating a proton thus acting as Bronstead acid with its conjugate base HPO42-

H3O+ is donating a proton thus acting as acid having a conjugate base H2O

PART (C): OPTION 'A'

H2PO4- can donate a proton thus acting as Bronstead acid with its conjugate base HPO42-

H2O is donating a proton thus acts as acid with its conjugate base OH-

PART (D): OPTION 'A'

NH4+ is donating a proton thus acts as acid with its conjugate base NH3

HNO2 is donationg a proton thus acts as acid with its conjugate base NO2-
