The correct order of reactivity towards nucleophilic addition (e.g. HCN) for the following benzaldehydes is

1. Abenzaldehyde $>$ 4-nitrobenzaldehyde $>$ 4-methoxybenzaldehyde $>$ 4-(dimethylamino)benzaldehyde
2. B4-(dimethylamino)benzaldehyde $>$ 4-methoxybenzaldehyde $>$ benzaldehyde $>$ 4-nitrobenzaldehyde
3. C4-nitrobenzaldehyde $>$ 4-methoxybenzaldehyde $>$ benzaldehyde $>$ 4-(dimethylamino)benzaldehyde
4. D4-nitrobenzaldehyde $>$ benzaldehyde $>$ 4-methoxybenzaldehyde $>$ 4-(dimethylamino)benzaldehyde
