NFIRS has three statements. Which statement is true?

• A. Statement 1 is true; statements 2 and 3 are false.
• B. Statement 2 is true; statements 1 and 3 are false.
• C. Statement 3 is true; statements 1 and 2 are false.
• D. All three statements are true.

Answer: (D)

The statements form a self-referential setup: each one says it is true and the other two are false. That creates a puzzle about consistency. If exactly one statement is true, that one being true makes its claim correct and forces the other two to be false, which matches their content as false statements. So having only one true statement is logically consistent. If two statements were true, each would require the third to be false, which would make the third false after all, a contradiction. If all three were true, each would say the others are false, which cannot happen. So the only logically possible situation is that exactly one of the three statements is true, and the other two are false. There isn’t a unique single correct choice among the first three based on the information given; any of the three could be the true one. The option claiming all three are true cannot be correct.
