Solution

The correct option is A $_{4}^{9} B e (α, n)_{6}^{12} C$
The abbreviated notation for the bombardment reaction in which neutron was first discovered is as follows:

Reaction: $_{4}^{9} B e +_{2}^{4} H e ⟶_{6}^{12} C +_{0}^{1} n$

Abbreviated notation: $_{4}^{9} B e (α, n)_{6}^{12} C$

$_{4}^{9} B e =$ Target nucleus

$α,_{2}^{4} H e =$ Bombarding particle

$n,_{0}^{1} n =$ Ejected particle

$_{6}^{12} C =$ Product nucleus

Hence, option A is correct.
