A nucleus decays by \( \beta^{+} \)emission followed by a gamma emission. If the atomic and mass numbers of the parent nucleus are \( Z \) and \( A \) respectively, the corresponding numbers for the daughter nucleus are respectively.
(A) \( Z-1 \) and \( A-1 \)
(B) \( Z+1 \) and \( A \)
(C) \( Z-1 \) and \( A \)
(D) \( Z+1 \) and \( A-1 \)
