Answer: (A)

Verified step by step guidance

1. Understand the function and characteristics of apocrine sweat glands. These glands are primarily found in areas such as the armpits and groin and are associated with hair follicles.
2. Recognize that apocrine sweat glands begin to function at puberty, which is a key distinguishing feature from eccrine glands that are active from birth.
3. Note that apocrine glands secrete a thicker, milky fluid that is rich in proteins and lipids, unlike the watery secretion of eccrine glands.
4. Understand that apocrine glands release their secretions through a process called exocytosis, which involves the fusion of vesicles with the plasma membrane to release their contents.
5. Compare the size and number of apocrine glands to eccrine glands. Apocrine glands are generally larger but less numerous than eccrine glands, which are distributed widely across the body.
