PREMONITION : MONITIONERP :: LINSEEDOIL : ?

The pattern followed is that the first three alphabets are written in reverse order and are appended at the end in the given code. Rest of the letters (from 4th onwards) are written as it is from first position.

Eg = PRE -> ERP (at the end)

Similarly, for LINSEEDOIL

First three letters, LIN -> NIL

and rest of the letters SEEDOIL -> SEEDOIL  (in the beginning)

Thus, LINSEEDOIL : SEEDOILNIL

=> Ans - (C)
