The four main skin types are dry, normal, combination, and oily. Option A, sensitive skin, is a common concern that can exist alongside any of the four skin types, but it is not considered one of the primary types. Option C, acne-prone skin, is also not an official skin type, but rather a common issue that can affect any of the four main skin types. Option D, aged skin, can also describe the skin at any of the four skin types, but does not define a specific type in itself. Option B, oily skin, refers to skin that produces excess oil and may have larger pores, making it different from dry, normal, or combination skin. Thus, it is the correct answer to complete the list of four skin types.
