Correct option is C
Concept: (+2, -3, +2, -3)
Explanation:
PLAY to RICV:
P to R: P (16) + 2 = R (18)
L to I: L (12) - 3 = I (9)
A to C: A (1) + 2 = C (3)
Y to V: Y (25) - 3 = V (22)
TREE to VOGB:
T to V: T (20) + 2 = V (22)
R to O: R (18) - 3 = O (15)
E to G: E (5) + 2 = G (7)
E to B: E (5) - 3 = B (2)
Now, let's apply the same pattern to BOOK:
B to D: B (2) + 2 = D (4)
O to L: O (15) - 3 = L (12)
O to Q: O (15) + 2 = Q (17)
K to H: K (11) - 3 = H (8)
So, 'BOOK' is coded as DLQH.
Alternate method as image solution:

Similarly,
BOOK can be written as DLQH.
