Definitely B) is correct since in case of B) n/p ratio is 1.07 which is said to be more stable than 1.27 .

But when β particle is released, the atom itself will change right? Will it not become Silicon atom?

@Asish α emission increases the n/p ratio..whereas β emission decreses it..initial n/p = 1.23
29Al13 → α + 25Na11 n/p = 1.27
29Al13 → β + 29Si14 n/p = 1.07
