Final answer:

Step-by-step explanation:
To reduce tangling of the hair while rinsing the relaxer, it is best to use cold water with medium pressure.
When hair is exposed to high temperatures, it can become weak and prone to breakage. Cold water helps to close the cuticle of the hair shaft, reducing frizz and tangling. Using medium pressure ensures that the water can effectively rinse out the relaxer without causing excessive tangling.
Therefore, the answer to the question is c) Cold water with medium pressure.
