B. 4
C. 6
D. 8

Answer

A

Explanation

2-Methylbutane on monochlorinationn gives four isomers of which I and III are chiral compounds.
`underset(I)(ClCH_(2)-overset(CH_(3))overset(|)(.^(**)C)H-CH_(2)CH_(3))" "underset(II)(CH_(3)-underset(Cl)underset(|)overset(CH_(3))overset(|)(C)-CH_(2)CH_(3))`
`underset(III)(CH_(3)-overset(CH_(3))overset(|)(C)H-underset(Cl)underset(|)overset(**)(C)H-CH_(3))" "underset(IV)(CH_(3)-overset(CH_(3))overset(|)(C)H-CH_(2)-CH_(2)Cl)`
