Thus the correct answer is Option A

Explanation:

In Lochner vs. New York (1905), the Supreme Court decided that a New York law setting most extreme working hours for dough punchers was unlawful. The Court held that the Constitution disallows states from meddling with most work contracts because the privilege to purchase and sell work is a principal opportunity ensured by the Fourteenth Amendment.

The choice, and the subsequent Lochner period it introduced prompted the revocation of numerous dynamic time and Great Depression laws controlling working conditions.
