$"Option B"$

In general, a carbon centre is stereogenic if it is bound to 4 different substituents, i.e. we look for $CR_1R_2R_3R_4$ .

$"2-bromobutane"$ fulfills this criterion: $H_3C-CH(Br)CH_2CH_3$ . What are the 3 groups attached to the chiral carbon?

$BrH_2C-CH_2CH_3$ , $H_3C-CH_2CHBrCH_2CH_3$ , and $C_6H_11Br$ do not contain a stereogenic or chiral carbon.

Which group contains a chiral carbon? A.A. "1-bromopropane""1-bromopropane". B.B. "2-bromopropane""2-bromopropane". C.C. H_3C−CH_2CHBrCH_2CH_3H_3C−CH_2CHBrCH_2CH_3. D.D. "cyclohexyl bromide""cyclohexyl bromide"
