Correct option is D
Given:
MP 14 is related to LS −1
NK 5 is related to MN −10
We need to identify the relationship and apply it to SW −1.

Logic: First letter decreased by 1 and second letter increased by 3, and the number is decreased by 15.
For MP 14 → LS −1:
The letter pair MP is transformed into LS.
M - 1 = L
P +3 = S
14 - 15 = -1
For NK 5 → MN −10:
The letter pair NK is transformed into MN.
N - 1 = M
K + 3= N
5 - 15 = -10
Now, applying this pattern to SW −1:
For SW −1:
S - 1 = R
W +3 = Z
-1 - 15 = -16
Final Answer: (D) RZ −16
