What will be the plain text corresponding to cipher text “RSEADC”

1.	What will be the plain text corresponding to cipher text “RSEADC” if with the number of columns are given to be 3 and route of reading is down the columns?(a) SACRED(b) DERSAC(c) REDSAC(d) SEDRACI have been asked this question during an interview.My question is taken from Cryptography in chapter Cryptography of Data Structures & Algorithms II
Answer» The CORRECT OPTION is (c) REDSAC The explanation is: For decryption we reverse the process USED in encryption. So we arrange the LETTERS of cipher text down the columns and then read the grid horizontally. R E D S A C So the resulting plain text is “REDSAC”.
