Dehydrohalogenation of Tert-Pentyl Bromide at Higher Temperatures Will Produce 2-Methyl-1-Butene

Dehydrohalogenation of tert-pentyl bromide at higher temperatures will produce 2-methyl-1-butene as the chief product when:

A) CH₃COONa is employed as the base.
B) KOH/C₂H₅OH is employed as the base
C) CH₃CH₂ONa/CH₃CH₂OH is employed as the base.
D) (CH₃) ₃COK/(CH₃) ₃COH is employed as the base.
E) any base is used,as long as the temperature is sufficiently high.
