Another question for reasoning. Plz answer..

Answer – d) RPCAITEC
Explaination:
In this question, the logic used is that the word is broken into pairs of two and then, positions of alphabets in those pairs are reversed.
For Example : REGISTER 
Step 1: Break this word in pairs of two alphabets.
             So,
             RE GI ST ER
Step 2: Reverse the positions of alphabets in each pair.
             So, RE ---- ER
                   GI   ----- IG
                   ST ----- TS
                    ER ----- RE
                Now, on combining above pairs, the required coded word comes out to be ERIGTSRE(which is the given                      option).
  Similarly for PRACTICE, the correct option is RPCAITEC
