    Electrons have mass 0

    Protons have mass 1

    Neutrons have mass 1

    (1) 0 is not greater than 1

    (2) 0 is not greater than 1

    (3) 1 is greater than 0

    (4) 1 is not greater than 1

    So the answer is (3) The mass of a proton is greater than the mass of an electron

    atoms are made of 3 types of subatomic particles - electrons, protons and neutrons

    mass of proton is 1 atomic mass unit and proton is also 1 atomic mass unit

    masses of protons and neutrons are very similar

    mass of an electron is 1/1840th of 1 atomic mass unit

    mass of electron is insignificant when compared to masses of neutrons and protons

    protons and neutrons have a larger mass than electrons

    from the given options correct answer is

    (3) The mass of a proton is greater than the mass of an electron
