Final answer:
D) Dry skin is the least likely skin type to have blemishes due to its lower oil production and fewer active sebaceous glands.
Step-by-step explanation:
The skin type that is least likely to have blemishes is dry skin.
Blemishes, typically referring to acne or pimples, occur when the hair follicles on the skin become clogged with oil, dead skin cells, and bacteria. Dry skin tends to produce less oil and has fewer active sebaceous glands compared to other skin types. This reduces the chances of clogging the pores and developing blemishes.
On the other hand, oily skin produces more oil, making the pores more prone to clogging and blemish formation. Normal skin and combination skin have moderate oil production, making them more susceptible to developing blemishes compared to dry skin.
