In a certain code, LOTUS is written as KPSVR. How can WATER be written in that code?

Correct option is C

Given:
LOTUS is written as KPSVR.

Logic: The pattern alternates between shifting -1 and +1 for each letter.
L to K: This is a shift of -1
O to P: This is a shift of +1
T to S: This is a shift of -1
U to V: This is a shift of +1
S to R: This is a shift of -1
So,
Using the same pattern for WATER:
W to V (shift -1)
A to B (shift +1)
T to S (shift -1)
E to F (shift +1)
R to Q (shift -1)
Thus, WATER is written as VBSFQ.
Correct answer: (c) VBSFQ
