B - All the people came to look at the richly clad young warrior, who walked with such a quick, light step.
This is an example of imagery as the reader is able to visualize the young warrior with fine items and a regal air.
For a, this would be incorrect as it's just a simple sentence to practically conclude a story.
C would be incorrect as this is more personification than anything. D is the same as it just explains the glare of a sun, possibly allowing the reader to feel the heat.
Hope this helps!
