What does "groundless" mean?

• A. Based on evidence
• B. Without a good reason
• C. Well-supported
• D. Fully justified

Answer: (B)

The term "groundless" refers to something that lacks a solid foundation or justification, thus meaning it is "without a good reason." This aligns with the idea that a claim or assertion described as groundless does not have the necessary evidence or rationale to support it. In contexts such as legal or logical arguments, if a statement is groundless, it suggests that there is no substantial basis for it, making it inherently unreliable or unsubstantiated.

Other options such as being based on evidence or well-supported suggest the opposite of groundlessness, indicating that there is an underlying rationale or proof for a claim, which does not apply here. Similarly, fully justified conveys a sense of strong support and reasoning, again contrasting with the meaning of groundless.
