In a certain code, FRACTION is written as FNAITCOR. How is QUANTITATIVE written in that code?

Given : FRACTION is written as FNAITCOR

The pattern followed is that the letters are odd positions (from left side) are in the same position but letters in even position are written in reversed order.

Letters at odd position = FATO : FATO

Letters at even position = RCIN : NICR

Similarly, for QUANTITATIVE,

Letters at odd position = QATTTV : QATTTV

Letters at even position = UNIAIE : EIAINU

Thus, final answer after merging letters at both position : QEAITATITNVU

=> Ans - (D)
