Verified step by step guidance

Step 1: Begin by identifying the function of each gland listed in the options. Sebaceous glands produce sebum, an oily substance that lubricates the skin and hair. Sudoriferous glands are sweat glands responsible for perspiration. Ceruminous glands produce earwax (cerumen). Mammary glands produce milk.

Step 2: Understand the context of acne. Acne is a skin condition caused by the clogging of pores, often due to excess sebum production, dead skin cells, and bacterial infection.

Step 3: Relate the function of sebaceous glands to acne. Since sebaceous glands produce sebum, excessive activity or blockage of these glands can lead to acne formation.

Step 4: Eliminate the incorrect options based on their functions. Sudoriferous glands, ceruminous glands, and mammary glands are not involved in sebum production or acne development.

Step 5: Conclude that the correct answer is 'sebaceous glands,' as they are directly associated with the production of sebum, which plays a key role in acne formation.
