Which of these reaction(s) will not produce Saytzeff product?

Difficult
Solution

Reaction (C) gives Hoffman product as the major product. The reason is the nature of the base. In option C , we can see that due to the bulky nature of t-butoxide it can abstract hydrogen from stearic free position only. Hence it disobeys satzeff rule.
