Final answer:
The purpose of applying wax to a client's hand is not to avoid hand odors; instead, it is intended for moisturizing and softening the skin. Wax can help make skin supple and prevent it from drying out. The correct option is D).
Step-by-step explanation:
The purpose of applying wax to the hand of a client is not to avoid hand odors.
Wax application serves various skin-care functions, like helping make skin supple, preventing skin from drying, and helping make skin soft. It is worth noting that while lotions often moisturize and soften the skin, their function does not routinely include providing protection from body odors.
In the context of the integumentary system, the hypodermis has several roles including protecting underlying organs, temperature regulation, being a source of blood vessels and storing energy long-term, but it does not provide odor protection.
Similarly, when considering the function of cosmetic products or moisturizers, they focus on skin hydration, using occlusives to retain moisture or humectants to draw water into the epidermis for a moisturizing effect, but they do not inherently prevent or mask odors. Option D) is the correct one.
