Step 1: Understanding the Question:
• The question asks under what condition a belief counts as a knowledge claim according to Wittgenstein.
Step 2: Detailed Explanation:
• As per the NTA final answer key, a belief is treated as a knowledge claim when it is logically possible for that belief to be false, i.e. it is a genuine, fallible claim that can be tested or doubted.
• Being subjectively acquired or socially accepted does not by itself make a belief a knowledge claim, and being absolutely true would leave no logical possibility of error.
Step 3: Final Answer:
The correct option is (C) It is logically possible for that belief to be false.
