Solution
The correct option is D II and III
(1-butene)(I) : Dehydration gives 2-butene as a major product.
(II) + (III) : Hofmann's Rule implies that steric effects have the greatest influence on the outcome of the Hofmann or similar eliminations. The loss of the β-hydrogen occurs preferably from the most unhindered (least substituted) position. So In both II and III, the major product would be 1-butene.
