For the following reaction identify the acid, base, conjugate acid and conjugate base.

◦ I = acid; II = base; III = conjugate base; IV = conjugate acid
◦ I = base; II = base; III = conjugate acid; IV = conjugate acid
◦
I = base; II = acid; | III = conjugate acid; IV = conjugate base |
◦
I = base; II = acid; | III = conjugate base; IV = conjugate acid |
◦ I = acid; II = base; III = conjugate acid; IV = conjugate base
