What is a key difference between a bath and a dip for animals?

The distinction between baths and dips primarily lies in the application and rinsing process. When performing a bath, the cleaning solution is applied to the animal's coat and is typically rinsed off after a designated period. This rinsing process helps to remove dirt, debris, and any residual cleaning agents, ensuring the animal's skin and fur are clean and free from irritation.

On the other hand, a dip involves immersing the animal in a solution that is not rinsed off afterward. Dips are commonly used for treatments involving insecticides, medicated solutions, or other therapeutic ingredients that need to remain on the animal's coat to be effective. The active ingredients in dips provide extended protection or treatment and are intended to remain for a certain duration to allow proper absorption.

This fundamental difference in how the solutions are used and whether they are rinsed makes option B the correct choice, highlighting the contrasting procedures associated with baths and dips in animal care.
