In a certain code language, GRASP is written as INOPQ and BROWN is written as RNSTU. How will SPARROW be written as in that code language?

Given: GRASP is written as INOPQ and BROWN is written as RNSTU.

This is direct coding pattern here.

there is no pattern following in the question, simply follow the pattern given in the question like G = I

G → I, R → N, A → O, S → P, P → Q
B → R, R → N, O → S, W → T, N → U
Then,

S → P, P → Q, A → O, R → N, R → N, O → S, W → T

Hence, SPARROW be written as PQONNST in that code language.​​

Thus, the correct answer is (d).
