In preventing tablet twinning, how many of the following statements are correct?

• A. ALL statements are correct
• B. ONLY ONE statement is correct
• C. TWO statements are correct
• D. THREE statements are correct

Answer: (C)

This set tests how to handle self-referential statements about the number of true statements.

If exactly one statement is true, the only one that can be true without producing a contradiction is the one that says only one statement is correct. If that one is true, the other three must be false, which makes the total number of true statements equal to one. That matches the claim and is self-consistent.

Trying counts of two, three, or four leads to contradictions: the statements about those exact counts would force incompatible truth values for the others, so no consistent scenario arises with those counts.

Therefore, the self-consistent solution is that exactly one statement is correct, i.e., the statement that declares only one statement is correct. The correct choice is the option that asserts that only one statement is correct. (The given answer listing that multiple statements are correct isn’t consistent with the logic.)
