Solution

The correct option is C Sodium methoxide and tert-butyl bromide

Alkoxide ions are both powerful nucleophiles and bases. Thus, when they are treated with a tert alkyl halide, they bring its dehydrohalogenation resulting in the formation of alkene. Hence, the alkyl halide taken must be tertiary.
