The correct option is C MOBILE
Given, RADIO is written as PYBGM. The coding pattern for the same is:
R −2−−−→ P
A −2−−−→ Y
D −2−−−→ B
I −2−−−→ G
O −2−−−→ M
Similarly, OQDKNG is coded as follows:
O −2−−−→ M
Q −2−−−→ O
D −2−−−→ B
K −2−−−→ I
N −2−−−→ L
G −2−−−→ E
Hence, OQDKNG is writen as MOBILE.
Therefore, option (D) is the correct answer.
