A nucleus of thorium-232 (90232Th^{232}_{90}\text{Th}90232Th) undergoes a decay sequence consisting of one alpha (α\alphaα) decay followed by two beta-minus (β−\beta^-β−) decays to form a daughter nucleus. Which of the following nuclides Y\text{Y}Y is an isotope of this daughter nucleus?
88228Y^{228}_{88}\text{Y}88228Y
90230Y^{230}_{90}\text{Y}90230Y
89231Y^{231}_{89}\text{Y}89231Y
92232Y^{232}_{92}\text{Y}92232Y
