Which of the following ciphered text would have used transposition cipher for encryption of the plain text "DATASTRUCTURE"?

Solution (By Examveda Team)

Option A: "DATAURCTTSRUE"
This option is a rearrangement of the letters in "DATASTRUCTURE". It has the same letters but in a different order, so it could be the result of a transposition cipher.

Option B: "TSDTCAUREUERT"
This option does not match the exact number of each letter in the plaintext. It includes extra 'T's and missing letters, so it is not a valid transposition cipher result.

Option C: "DTAURCTEDSUTRR"
This option does not match the exact number of each letter in the plaintext. It includes extra 'D's and missing letters, so it is not a valid transposition cipher result.

Option D: "RTEUDAATSTRCR"
This option contains repeated letters and is missing some letters from the original plaintext. It does not match the plaintext letter count, so it is not a valid transposition cipher result.

Conclusion:
The correct options where the ciphertext is a rearrangement of "DATASTRUCTURE" using a transposition cipher is:
Option A: DATAURCTTSRUE
