Radioactivity — practice question

A radioactive decay process can be shown as follows. $^{{233}}_{{91}}\text{Pa} \rightarrow ^{{233}}_{{92}}\text{U}$ This equation is not complete. During this decay, the nucleus is altered by

• Aabsorbing a neutron.
• Babsorbing a proton.
• Cemitting an $\alpha$-particle.
• Demitting a $\beta$-particle.
