Which of the following best describes the function of an anti-perspirant?

The primary function of an anti-perspirant is to minimize perspiration. Anti-perspirants work by temporarily blocking the sweat glands, reducing the amount of sweat that reaches the skin's surface. They typically contain aluminum-based compounds that dissolve in the sweat and form a gel-like plug in the glands, preventing sweating in specific areas, particularly under the arms. This is crucial for individuals wishing to manage or reduce sweat during daily activities, making option B the most accurate description of an anti-perspirant's function.

While other options may seem relevant in the context of body care, they do not accurately define the purpose of an anti-perspirant. Masking body odor would be the role of deodorants rather than anti-perspirants. Promoting sweating is contrary to the function of an anti-perspirant, as it aims to reduce sweat production. Exfoliating skin pertains to the removal of dead skin cells, which is unrelated to the function of an anti-perspirant. Therefore, the emphasis on minimizing perspiration clearly highlights the correct understanding of what an anti-perspirant does.
