What Was the Result in Ragsdale V

What was the result in Ragsdale v.Wolverine World Wide,involving whether the Department of Labor could validly institute a regulation giving an employee the right to an additional twelve weeks of family or medical leave if the employer failed to notify the employee that the twelve weeks of leave provided by the Family and Medical Leave Act ran concurrently with the thirty weeks of paid disability leave provided by the employer?

A) The U.S. Supreme Court invalidated the regulation because it granted entitlements not set forth in the Family and Medical Leave Act and that were inconsistent with the purpose of the Act.
B) The U.S. Supreme court upheld the regulation as a valid exercise of the Department of Labor's power.
C) The U.S. Supreme Court invalidated the regulation because it had not first been approved by a federal judge and also because it granted entitlements not set forth in the Family and Medical Leave Act.
D) The U.S. Supreme Court invalidated the regulation because it had not first been approved by the executive branch.
