{'oral contraceptive': [1, 0, 0, 0], 'progesterone': [0, 0, 0, 2], 'hormone': [6, 1, 1, 1], 'testosterone': [1, 0, 0, 0], 'aldesterone': [1, 0, 0, 0], 'cortisone': [3, 0, 1, 1]}

The correct answer to the question is option 2: Progesterone. Progesterone is a hormone that is used in oral contraceptives, also known as birth control pills. These pills contain synthetic forms of progesterone, called progestins, which work by preventing ovulation, thickening the cervical mucus to block sperm, and thinning the lining of the uterus to make it less receptive to a fertilized egg.

Option 1, cortisone, is a different hormone that is used to treat inflammation and immune system disorders. Option 3, testosterone, is a male sex hormone and is not used as an oral contraceptive. Option 4, aldosterone, is a hormone that regulates electrolyte balance and blood pressure and is also not used as an oral contraceptive.

It is important to note that the answer provided in the question is generally correct.
