The correct option is D RRTBQF
Given, TRIANGLE is coded as SSHBMHKF. The coding pattern for the same is:
T −1−−−→ S
R +1−−−→ S
I −1−−−→ H
A +1−−−→ B
N −1−−−→ M
G +1−−−→ H
L −1−−−→ K
E +1−−−→ F
Similarly, SQUARE is coded as follows:
S −1−−−→ R
Q +1−−−→ R
U −1−−−→ T
A +1−−−→ B
R −1−−−→ Q
E +1−−−→ F
Hence, SQUARE is coded as RRTBQF.
Therefore, option (C) is the correct answer.
