In the given letter-cluster pairs, the first letter-cluster is related to the second letter-cluster following a certain logic. Study the given pairs carefully, and from the given options, select the pair that follows the same logic.
TOP: VRU
XOR: ZRW

​Pair 1: TOP → VRU

T → V: Move forward by 2 places.

O → R: Move forward by 3 places.

P → U: Move forward by 5 places.

Pair 2: XOR → ZRW

X → Z: Move forward by 2 places.

O → R: Move forward by 3 places.

R → W: Move forward by 5 places.

Logic: For each letter in the first cluster, the corresponding letter in the second cluster is obtained by adding 2, 3, and 5, respectively, to their places in the alphabet.

By Option A: QIP → SLV

Q → S: Forward by 2 places

I → L: Forward by 3 places

P → V: Forward by 6 places

Option B: NET → PGY

N → P: Forward by 2 places

E → G: Forward by 2 places

T → Y: Forward by 5 places

This does not match the logic. Discard this option.

Option C: NOR → PRW

N → P: Forward by 2 places

O → R: Forward by 3 places

R → W: Forward by 5 places

This matches the logic. Keep this as a potential answer.

Option D: TOM → VRQ

T → V: Forward by 2 places

O → R: Forward by 3 places

M → Q: Forward by 4 places

This does not match the logic. Discard this option.

Thus, correct option is (a).
