Answer: B

The first step is to determine the question type.

According to the question method "most accurately showing the absurdity of the above reasoning", it is determined to be a parallel structure.

The second step is to analyze the logical fallacy of the question.

According to Socrates’ words, it can be seen that Socrates knew one thing and did not know another thing, and his fallacy was “self-contradiction”.

The third step is to analyze the options.

Item B: On one side of the card, it says "The sentence on the back of the card is correct", and on the other side it says "The sentence on the back of the card is wrong". These two sentences are self-contradictory and are inconsistent with the logic of the question. The fallacies are the same and consistent;

Item C: "I would rather die than surrender" discusses whether you are willing to surrender, while "able to bend and stretch" discusses whether you can surrender. The fallacy in this item is a stolen concept, which is a logical fallacy with the question Different, excluded;

Item D: The "contradiction" mentioned by A is the "conflict" in real life, and the "contradiction" mentioned by B refers to the "unity of opposites" in philosophy. The logic of this item The fallacy is a substitution of concepts, which is different from the logical fallacy in the question and should be eliminated.
