Solution:

Given information:
- 7 people - P, Q, R, S, T, W and X
- Sitting in a straight line facing north
- R sits at one of the extreme ends of the line
- T has as many people sitting on his right, as on his left
- S sits third to the left of X
- Q sits on the immediate left of W
- Q does not sit at any of the extreme ends of the line

To find:
- If all the people are made to sit in alphabetical order from right to left, the positions of how many people will remain unchanged?

Arranging the given information in a diagram:
```
(R) _ _ _ _ _ _ (T) _ _ _ _ _ _ (S) _ _ _ _ _ _ (X) _ _ _ _ _ _ (Q) _ _ _ (W) _ _ _ (P)
```
- R sits at one of the extreme ends of the line.
- T has as many people sitting on his right, as on his left. Therefore, T must sit in the middle of the line.
```
(R) _ _ _ _ _ _ (T) _ _ _ _ _ _ (S) _ _ _ _ _ _ (X) _ _ _ _ _ _ (Q) _ _ _ (W) _ _ _ (P)
```
- S sits third to the left of X.
```
(R) _ _ _ _ _ _ (T) _ _ _ _ _ _ (S) _ _ _ (X) _ _ _ (Q) _ _ _ (W) _ _ _ (P)
```
- Q sits on the immediate left of W.
```
(R) _ _ _ _ _ _ (T) _ _ _ _ _ _ (S) _ _ _ (X) _ _ _ (Q) _ _ (W) _ _ _ (P)
```
- Q does not sit at any of the extreme ends of the line. Therefore, P must sit at the other extreme end of the line.
```
(R) _ _ _ _ _ _ (T) _ _ _ _ _ _ (S) _ _ _ (X) _ _ _ (Q) _ _ (W) _ _ _ (P)
```

Now, arranging the people in alphabetical order from right to left:
```
(P) _ _ _ _ _ _ (W) _ _ _ (Q) _ _ _ (X) _ _ _ (S) _ _ _ (T) _ _ _ (R)
```
- Only one person's position remains unchanged, which is Q.

Therefore, the answer is option (B) One.
