Significant most closely means which of the following?

• A. Quite important
• B. Suggesting or showing a meaning
• C. Noticeable or detectable
• D. Noteworthy

Answer: (D)

Significant is used when something stands out and deserves attention because of its importance or impact. Noteworthy fits this sense perfectly because it means deserving notice or remark due to being important or notable. In everyday usage, you’d call an important discovery or an event that has real effects noteworthy, rather than merely describing it as visible or merely implying meaning.

The other options don’t align as closely. One focuses on importance but doesn’t capture the idea of being notable enough to attract attention. Another emphasizes meaning or implication rather than importance, and the last highlights perceptibility rather than significance. So, the closest match for significant is noteworthy.
