Final answer:
Robert Frost's "The Road Not Taken" uses metaphor and symbolism as its central figurative language, with the roads serving as symbols for life choices, making option (D) Symbolism the correct answer.
Step-by-step explanation:
The poem "The Road Not Taken" by Robert Frost employs several types of figurative language, but its central mechanic is metaphor. The road in the poem represents the choices we make in life, and the act of choosing one path over another is a metaphor for making life decisions. Frost doesn't compare the roads to anything with the words 'like' or 'as,' which rules out simile.
In addition, the poem also uses symbolism. The roads themselves are symbols for different courses in life that one can take. The road 'less traveled' symbolizes the less conventional or more difficult choice, which is often the essence of making a tough decision.
Symbolism is the primary figurative language at work here, as it imbues the poem with deeper meanings beyond the literal. The final answer to what type of figurative language is used most prominently in "The Road Not Taken" would be option (D) Symbolism.
