Step-by-step explanation:
Answer A
Correct. The sentence containing “brightest blazes,” “kindled,” and “unexpected sparks” illustrates the first sentence of the paragraph, which reads, “Pleasure is very seldom found where it is sought.” By developing a metaphor that compares pleasure to a fire that starts unexpectedly, the author emphasizes the spontaneous (occurring naturally without any apparent external cause or influence) nature of pleasure.
