(B) The dehydration of $2-$butanol $(CH_3-CH(OH)-CH_2-CH_3)$ involves the removal of a water molecule to form an alkene.According to the $Saytzeff$ rule,in elimination reactions,the more substituted alkene (the one with more alkyl groups attached to the double-bonded carbons) is the major product.In this case,$2-$butene $(CH_3-CH=CH-CH_3)$ is more substituted than $1-$butene $(CH_2=CH-CH_2-CH_3)$,hence it is the major product.

Formation of $2-$butene as the major product by dehydration of $2-$butanol is according to:
