A nucleus of carbon-10, ¹⁰C, decays by beta-emission to form a nucleus of boron-10, ¹⁰B. For this decay process, what is the change to a nucleon and what is the change in the quark composition of the nucleon?
Achange to nucleon proton to neutron, change in quark composition down becomes up
Bchange to nucleon proton to neutron, change in quark composition up becomes down
Cchange to nucleon neutron to proton, change in quark composition down becomes up
Dchange to nucleon neutron to proton, change in quark composition up becomes down
