Verity is a good virtue for human life.

The correct option that can substitute the underlined word "Verity" in the given sentence is Truth.

Analysis & Explanation:
1. Understanding the Word: The word "verity" is a noun derived from the Latin word veritas, which translates directly to "truth." In English, "verity" refers to the quality of being true, factual, or conforming to reality.
2. Examining the Sentence: The sentence is "Verity is a good virtue for human life." Here, the sentence expresses that being truthful or adhering to the truth is a valuable moral quality (virtue) in human existence.
3. Evaluating the Options:
- Truth: This is a direct synonym of "verity." Substituting "Verity" with "Truth" yields: "Truth is a good virtue for human life," which preserves the exact meaning and maintains correct grammatical structure.
- Information: This refers to facts or data provided or learned, which does not carry the moral weight or meaning of truthfulness.
- Knowledge: This refers to skills and facts acquired through experience or education, which is distinct from the concept of truthfulness.
- Cooperation: This refers to the action of working together to the same end, which is a different virtue altogether.

Therefore, Truth is the most appropriate substitute.
