The pattern followed is, The first term is O*M. After the first term there is a gap of one and then the second term in the series is C$T. After the second term there is a gap of one and then the third term in the series is @SL. After the third term there is a gap of one and then the fourth term in the series is #UD. After the fourth term there is a gap of one and , The fifth term will be ‘! L V’. The complete pattern is, Hence, “! L V” is the correct answer.
