Explanation:

Chemical sterilization is an alternative to heat - based sterilization methods (like autoclaving which uses heat and steam). Instruments that are sensitive to heat and steam can't be sterilized using heat - based methods, so chemical sterilization is suitable for them.

• Option 1: Chemical sterilization isn't related to cold sensitivity; cold - sensitive instruments don't imply chemical sterilization is needed.
• Option 2: Chemical sterilization involves chemicals (often in liquid form), so it's not for instruments that must be dry.
• Option 4: Chemical sterilization is for sterilization, so it's not for instruments that don't need sterilization.

Answer:

C. For instruments that are sensitive to heat and steam
