Which of the following is a Class I topical corticosteroid?

Explanation:
Class I topical corticosteroids are the most potent, used for severe inflammatory skin conditions and for short durations because they carry higher risk of thinning skin and systemic absorption. Clobetasol is the quintessential example of a Class I (super-potent) steroid. Hydrocortisone is a low-potency option suitable for mild dermatitis, triomcinolone is a mid-range potency steroid, and betamethasone is potent but not in the top Class I tier. Therefore, the correct choice is clobetasol.
