Consider the following:
1. Aerosols
2. Foam agents
3. Fire retardants
4. Lubricants
In the making of how many of the above are hydrofluorocarbons used?
Consider the following:

4. Lubricants
In the making of how many of the above are hydrofluorocarbons used?
The answer is (c), only three. Hydrofluorocarbons (HFCs) are man-made chemicals that are used in a variety of products, including aerosols, foam agents, and fire retardants. HFCs are also used as refrigerants, but they are being phased out in many countries due to their environmental impact. HFCs are not used in the making of lubricants. Lubricants are typically made from petroleum-based products or synthetic oils. Therefore, the correct answer is (c), only three.
