Preethi arranges different colours of teddy bears in her bedroom in two parallel rows facing each other such that four teddies are in each row. Orange, Yellow, Grey and Brown teddies are in Row 1 facing north, while Red, White, Black and Pink teddies are in Row 2 facing south. Orange teddy is adjacent to the Grey teddy. Pink teddy does not face the Orange one. White teddy faces the one that is second to the right of the Grey teddy. The Black one is second to the right of the Pink teddy. The Brown teddy is not at any of the corners. The Orange teddy is not at any of the extreme ends. The Grey teddy faces the Red one. How many teddies are there between Red and White teddies?

South: Red, White, Black and Pink

North: Orange, Yellow, Grey and Brown

1. Orange teddy is adjacent to the Grey teddy.

2. The Grey teddy faces the Red one.

3. Pink teddy does not face the Orange one.

4. White teddy faces the one that is second to the right of the Grey teddy.  

5. The Orange teddy is not at any of the extreme ends. 

Based on the above statement, Case II is eliminated.

6. The Black one is second to the right of the Pink teddy.

7. The Brown teddy is not at any of the corners.

Yellow, the only Teddy left, will occupy the only possible position for him in the arrangement.

Clearly, there is only one teddy in between Red and White teddy.

Hence, 'one' is the correct answer.
