In a certain code language, 'QUART' is written as 'RSBPU' and 'LEMON' is written as 'MCNMO'. How will 'JUMPY' be written in that language?

Given: 'Q​UART' is written as 'RSBPU'

'LEMON' is written as 'MCNMO'

Logic: 1st letter + 1,2nd letter - 2 ,  3rd letter  + 1 , 4th letter - 2 , 5th letter + 1 

Q + 1 = R, U - 2 = S, A + 1 = B, R - 2 = P, T + 1 = U

L + 1 = M, E - 2 = C, M + 1 = N, O - 2 = M, N + 1 = O

Similarly, for JUMPY

J + 1 = K, U - 2 = S, M + 1 = N, P - 2 = N, Y + 1 = Z

The code of JUMPY is KSNNZ

Thus, correct option is (c).
