Given below are two statements :
one is labelled as
Assertion (A) and the other is labelled as

Assertion (A) :
TCP uses sequence numbers to ensure reliable, in-order delivery of data segment.
Reason (R) :
Sequence number helps detect packet duplication and reordering in transmission.
In the light of the above statements, choose the most appropriate answer from the options given below :

• A. Both (A) and (R) are correct and (R) is the correct explanation of (A)
• B. Both (A) and (R) are correct but (R) is not the correct explanation of (A)
• C. (A) is correct but (R) is not correct
• D. (A) is not correct but (R) is correct

Hint:

Think of sequence numbers like page numbers in a book. If you drop the book and the pages scatter, you can only put them back in order because the numbers tell you exactly where each page belongs!
