Option (b) is correct

"No human beings are mortal" and "Some human beings are mortal" are contradictory to each other.

In statement B, it is claimed that no human beings are mortal, implying that there are no human beings who possess the quality of mortality. On the other hand, in statement C, it is stated that some human beings are mortal, indicating that there exists at least one human being who possesses the quality of mortality.

These two statements cannot both be true at the same time because they make conflicting claims about the same subject. Therefore, option (b) is the correct answer.

विकल्प (b) सही है।

विरोध के पंरपरागत वर्ग के अनुसार, कथन (B) “कोई भी मनुष्य नश्वर नहीं होता” और कथन (C) “कुछ मनुष्य नश्वर होते हैं” परस्पर व्याघाती हैं।

• कोई भी मनुष्य नश्वर नहीं होता [E]
• कुछ मनुष्य नश्वर होते हैं [I]

‘E’ से ‘I’ का संबंध ‘व्याघाती’ (contradictory) का है।
