Answer:
The answer is letter C: After brushing on another stroke of fiery crimson, the canvas looked complete.
Step-by-step explanation:
Participial phrases contain participles, which are words formed from verbs, but act as adjectives in a sentence. These "adjectives" end in "-ing", "-d", "-t", or "-n".
This is the exact same function of a participial phrase, but with all its complements. We can see a clear example of it in sentence C: After brushing on another stroke of fiery crimson, the canvas looked complete. In this case, the verb "brushing" is modifying the noun "canvas".
