After one

\alpha

-decay and two consecutive

\beta

-decays, the daughter nucleus is an isotope of the

View answer and explanation

Correct option: A

same element

Option A is correct because an alpha decay reduces the atomic number by 2, and each beta decay increases it by 1. Thus, after one alpha and two beta decays, the atomic number is the same as the original element, making it an isotope.
