The question is incomplete here is the complete question"Many chemical warfare maybe not the Joker's venom from the Batman comics). In turn, these intermediates can damage DNA by what type of chemical reaction? reagents readily convert into reactive 3-membered ring intermediates (although Your answer a. Elimination b.SN1 c.SN2 d.None of the above

(C) SN2

Explanation:

SN2 is a bimolecular nucleophilic substitution reaction and proceed with an intermediate compound. The nucleophile attacks the electron deficient carbon (donate electron to it) and replaces the previously attached electronegative group to create a highly reactive 3-membered intermediate ring in SN2 reactions. While SN1 are unimolecular reactions and the rate of reaction is dependent on only one reactant. Throughout WWI, Where the soldiers were killed by mustard gas, SN2 reaction was employed.

The problem here is that according to aufbau principle before 3d orbital 4s subshell comes.after filling 3p orbital with electrons you have 4 electrons left, you place two in 4s with opposite spin and the other two in 3d in any of its two orbitals of total five orbitals with the same spin.
