💡 Explanation
## **Core Concept**
Ethylene oxide is a widely used agent for sterilization, particularly effective against bacteria, viruses, and fungi. It works by alkylating DNA, thereby inhibiting microbial replication. This method is especially useful for heat-sensitive materials.
## **Why the Correct Answer is Right**
The correct answer, **D. Heat sensitive materials**, is right because ethylene oxide is specifically used for sterilizing materials that cannot withstand high temperatures, such as plastics, rubber, and certain types of medical equipment. Its ability to penetrate packaging materials and sterilize the contents without damaging the products makes it highly valuable.
## **Why Each Wrong Option is Incorrect**
