Explanation:

- Let's map the points:

- Point P is 10m north of Q.

- Point Q is 15m west of R.

- Point S is 10m north of R.

- Point S is also 25m north of T, making S much further up.

- Point W is 8m east of S.

- Point U is 8m east of T.

- Point U is 20m south of V.

- Now, let's consider each option:

- Option 1: PQ refers to a vertical northward movement of 10m.

- Option 2: SR also denotes a vertical southward movement of 10m.

- Option 3: ST indicates a vertical northward movement of 25m.

- Option 4: VU denotes a vertical southward movement of 20m.

- Option 5: RV is horizontal; Q is 15m west of R, and there's no direct V-R relationship.

- The odd one out is RV as it consists of a horizontal orientation, whereas the others consist of vertical orientations.

- Option:5 - RV
