Solution

The correct option is B
Statement 5
कथन 5

We can determine the correct order with the help of the first 4 statements alone. But we cannot say the same when any of the statements are replaced by statement 5. So, statement 5 is the redundant one.

हम केवल प्रथम 4 कथनों की मदद से सही क्रम निर्धारित कर सकते हैं। परंतु जब इनमें से कोई भी कथन 5 द्वारा प्रतिस्थापित किया जाता है, तो हम ऐसा नहीं कह सकते। अतः, कथन 5 निरर्थक है।
