Final answer:
Disinfected tools and multi-use supplies should be stored in a clean, dry place to prevent microbial growth and ensure the longevity of the tools.
Step-by-step explanation:
The correct answer to the question of where to store disinfected tools and multi-use supplies is c) Clean, dry place. This environment is least favorable for the growth and survival of microbes. Storing tools and supplies in a dark, cool place or a warm, humid place might encourage microbial growth, while sun exposure could degrade the materials over time. Medical specimens can be stored at ultra-low temperatures for long periods, as depicted in the given reference material. However, when it comes to disinfected tools and supplies, a clean and dry environment is essential.
