The correct answer is: B.Imagery.

The author is using imagery to create a vivid picture in the reader's mind. The description of "tiny splinters of ice in the air, fine as dust, that gave off myriads of bright colors" appeals to the reader's senses, particularly sight, and helps them imagine the scene in a clear and detailed way. This is characteristic of imagery, which uses descriptive language to create sensory experiences.
