Answer
The correct answer is A. one of Harding’s cabinet members illegally leased oil reserves.
Explanation
President Warren G. Harding was affected by the scandal though not directly implicated in it. When the president changed the supervision of the naval oil reserve lands to the department of the Interior from the navy, the secretary allowed Harry Sinclair from the Mammoth Oil Company to have exclusive rights to the Teapot Dome reserves in Wyoming. Another oil company was given a similar deal under secret leases. President Harding canceled the leases and the Supreme court ruled that the transfer process of authority that was performed by Harding was illegal.
