### Analyzing the Options

1. **Horizontal**: This term refers to something that is level or parallel to the ground. While light can be horizontal, it is not a definitive term to describe its behavior in a uniform medium.

2. **Parallel**: This term indicates lines that are equidistant from each other and will never meet. Light does not necessarily travel in parallel lines; it can diverge or converge depending on various factors like lenses or mirrors.

3. **Perpendicular**: This describes two lines that intersect at a right angle (90 degrees). Light does not inherently travel perpendicularly unless influenced by other phenomena like reflection.

4. **Straight**: This term refers to the most direct path with no bends or curves. Light travels straight in a uniform medium, making this option strongly aligned with the behavior of light.

### Conclusion

Given these analyses, the best option for how light travels through a uniform substance is **d. Straight**.
