Explanation / Answer

Skin changes color usually because there’s something going on in the body. For example, a person may look yellow because of liver problems, blue because of breathing problems, bruised because of blood disorders, or red because of skin problems. Changes in the skin can be due to tumor growth, sun exposure, or the side effects of treatment. Some color changes may improve over time, while others may be long lasting

The sebaceous, or oil-producing, glands of the skin go into overdrive during puberty, thanks to the influence of sex hormones. As noted in a “Clinical View” sidebar to this chapter, that oil production can get so intense it actually clogs sebaceous glandular ducts, thus forming a variety of skin deformations and discolorations called blackheads, whiteheads, cysts, nodules, pustules, or the catchall word acne.

Hence, the correct option is (b), blocked sebaceous glands.
