What is the term for something that is not genuine or is false?

The term that describes something that is not genuine or is false is "spurious." This word is often used to denote something that appears to be valid or true but is actually misleading or counterfeit. For example, spurious arguments or claims may rely on faulty reasoning or misinformation, making them unreliable.

In contrast, the other choices refer to concepts that do not align with the idea of falseness. "Factual" pertains to information that is based on facts and is therefore authentic and true. "Actual" refers to something that is real or existing in fact, rather than being fictional or untrue. "Transparent" typically suggests openness and clarity, signifying honesty rather than deception. This further clarifies that spurious is the only term among the options that directly signifies a lack of genuineness or truth.
