according to bronsted lowry theory an acid is a and a base is a , respectively.

1. proton acceptor, proton donor
2. proton donor, proton acceptor
3. neutron donor and neutron acceptor
4. none of the above

Explanation:

The Brønsted - Lowry theory defines an acid as a substance that donates a proton ($\ce{H+}$) and a base as a substance that accepts a proton. So we need to find the option that has "Proton donor" for acid and "Proton acceptor" for base. Option 1 has them reversed. Option 3 is incorrect as Brønsted - Lowry theory is about protons, not neutrons. Option 2 correctly states that an acid is a proton donor and a base is a proton acceptor.

Answer:

1. Proton donor, Proton acceptor
