In a certain code language, SPIDER is written as RNHBDP. How will QUESTION be written as in that language?

Correct option is D

By comparing each letter of SPIDER with RNHBDP:
S → R (shift -1)
P → N (shift -2)
I → H (shift -1)
D → B (shift -2)
E → D (shift -1)
R → P (shift -2)
The pattern alternates between shifting by -1 and -2 for each successive letter.
Applying this same pattern to QUESTION:
Q → P (shift -1)
U → S (shift -2)
E → D (shift -1)
S → Q (shift -2)
T → S (shift -1)
I → G (shift -2)
O → N (shift -1)
N → L (shift -2)
Thus, QUESTION is encoded as:
Answer: (d) PSDQSGNL
