(B) The reaction is the acid-catalyzed dehydration of butan-$2$-ol $(CH_3CH_2CH(OH)CH_3)$ using conc. $H_2SO_4$ and heat.This reaction proceeds via an $E1$ mechanism involving the formation of a secondary carbocation $(CH_3CH_2CH^+CH_3)$.This carbocation can undergo elimination of a proton from adjacent carbons to form alkenes.$1$. Removal of a proton from $C_1$ gives but-$1$-ene $(CH_3CH_2CH=CH_2)$.$2$. Removal of a proton from $C_3$ gives but-$2$-ene $(CH_3CH=CHCH_3)$.But-$2$-ene exhibits geometrical isomerism,existing as both $cis$-but-$2$-ene and $trans$-but-$2$-ene.Therefore,the possible products are but-$1$-ene,$cis$-but-$2$-ene,and $trans$-but-$2$-ene,totaling $3$ products.
