The apocrine gland is primarily responsible for body odor due to the unique characteristics of its secretion. These glands are primarily located in areas such as the armpits and groin, and they become active during puberty. The sweat produced by apocrine glands contains proteins and fatty acids, which, when broken down by bacteria on the skin, produce the characteristic odors associated with body odor. In contrast, eccrine glands primarily produce a more watery and less odorous sweat that is primarily involved in thermoregulation, while sebaceous glands secrete sebum, which is more associated with skin lubrication and does not contribute significantly to body odor. Thus, the apocrine gland is distinctly linked to body odor, making it the correct answer.
