In a certain code language, GERMINATION is written as IMGRENNOAIT. How is ESTABLISHED written in that code?

A BEATSLDEIHS
B BAETSLEDIHS
C BATESLDEIHS
D BAETSLDEIHS
E None of these

Correct Answer: BAETSLDEIHS

The middle letter remained unaltered in the code. Let us label the five letters before the middle letter as well as those after it, from 1 to 5. Then, the code contains the letters of each group in the order 5, 4, 1, 3, 2.
Thus, we have :
ESTABLISHED => BAETSLDEIHS
12345/12345 => 54132/54132
