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

1.	What will be the plain text corresponding to cipher text “BPKYFS” if playfair cipher is used with keyword as “SECRET” (assuming j is combined with i)?(a) INDIAN(b) WORLD(c) DOLLAR(d) HELLOThe question was asked in an interview for job.I'm obligated to ask this question of Cryptography in chapter Cryptography of Data Structures & Algorithms II
Answer» Right answer is (C) DOLLAR The explanation is: To DECRYPT the message we FOLLOW the reverse procedure. The table is formed in the same manner. APPLYING this we get the plain text to be “DOLLAR”.
