Explanation:

- Arrange the boxes in a 3x3 matrix based on given instructions.

- Box S is above Box G and southeast of Box K.

- Box C is in the same row as Box K but not near Box S.

- Box Y is above Box F.

- Box L is in the same column as Box K but southwest of Box S.

- Box C and Box Y are not in the same column.

- Box V is southwest of Box Y and below Box I.

- Box G is southeast of Box I.

Now identify the odd one out:

- Option 1: Box C - Fits above conditions.

- Option 2: Box G - Fits above conditions.

- Option 3: Box S - Fits above conditions.

- Option 4: Box Y - Does not fit a pattern like the others.

- Option 5: Box V - Fits above conditions.

The odd one out is Box Y, as it doesn't fit as seamlessly within the relationships.

Option 4: Y is the odd one out.
