Answer: c. The decision loomed ahead of him like a gathering storm.
Explanation:
Figurative language refers to when a real life situation is compared to a hypothetical situation in order to show the gravity of the real life situation. Figurative language examples included metaphors and similes.
Option C contains a simile due to its use of the word "like" to compare the decision being faced to a gathering storm. This shows that the decision ahead of Antonio was a difficult one because storms gathering ahead of a person would mean that the person is about to be in a difficult position.
