Let a, c and d are the other entities involved in the reaction

p is the projectile

\begin{aligned} &\mathrm{a}+\mathrm{p} \rightarrow \mathrm{c}+\mathrm{d} \\ &\mathrm{Q}=\mathrm{k}_{c}+\mathrm{k}_{\mathrm{d}}-\mathrm{k}_{\mathrm{p}} \\ &\mathrm{Q}+\mathrm{k}_{\mathrm{p}}=\mathrm{k}_{c}+\mathrm{k}_{\mathrm{d}} \\ &\mathrm{Q}+\mathrm{k}_{\mathrm{p}}>0 \end{aligned}

Hence the correct option is 4
