In a certain code, MARKET is written as NCUOJZ. Using the same rule, how will STOCK be written?
STOCK is coded as TVRGP. The rule shifts the first letter forward by 1, the second by 2, the third by 3 and so on. Applying shifts of 1 to 5 gives T, V, R, G and P respectively.

Explanation
In MARKET the shifts are +1, +2, +3, +4, +5, +6 by position (M to N, A to C, R to U, K to O, E to J, T to Z). For STOCK apply +1, +2, +3, +4, +5: S to T, T to V, O to R, C to G, K to P. The code is TVRGP. TVRGQ wrongly shifts the last letter by 6.
