The correct option is C QNMRNA
Given, ROAST is coded as PQYUR.
Here each letter is coded as:
R −2−−−→ P
O +2−−−→ Q
A −2−−−→ Y
S +2−−−→ U
T −2−−−→ R
Similarly, SLOPPY will be coded as:
S −2−−−→ Q
L +2−−−→ N
O −2−−−→ M
P +2−−−→ R
P −2−−−→ N
Y +2−−−→ A
Therefore, the word 'SLOPPY' is coded as 'QNMRNA'.
Hence, option (C) is the correct answer.
