The correct answer is: A. cold and humid.
Static electricity is a buildup of electrical charge on an object. It can occur when two objects rub together, such as when you walk across a carpet and then touch a doorknob. The friction between your shoes and the carpet causes electrons to transfer from the carpet to your shoes. This leaves your shoes with a negative charge and the carpet with a positive charge.
The amount of static electricity that builds up depends on a number of factors, including the type of materials involved, the amount of friction, and the humidity. In general, static electricity is more likely to build up in dry environments. This is because dry air does not conduct electricity as well as humid air. As a result, the electrons that are transferred from one object to another are more likely to stay on the object, rather than flowing back to the other object.
In cold environments, the air is even drier than in warm environments. This makes it even more likely that static electricity will build up. In addition, cold objects tend to be more conductive than warm objects. This means that they are more likely to attract electrons from other objects.
As a result, static electricity is most likely to thrive in cold and humid environments. This is because these environments provide the ideal conditions for the buildup of electrical charge.
Here is a brief explanation of each option:
- Option A: cold and humid. This is the correct answer. As explained above, static electricity is more likely to build up in cold and humid environments.
- Option B: warm and humid. This is not the correct answer. While humid environments do promote the buildup of static electricity, warm environments do not.
- Option C: warm and dry. This is not the correct answer. Dry environments do not promote the buildup of static electricity.
- Option D: cold and warm. This is not the correct answer. Static electricity is not more likely to build up in cold and warm environments.
- Option E: cold and dry. This is not the correct answer. Static electricity is most likely to build up in cold and humid environments.
