(C) In the dehydrohalogenation of $2$-fluorobutane with alcoholic $KOH$,the reaction follows Hofmann's rule.Since $F^-$ is a poor leaving group,the transition state has significant carbanion character.The more stable carbanion is formed at the terminal carbon (primary carbon),leading to the formation of But$-1-$ene $(CH_3-CH_2-CH=CH_2)$ as the major product.
