Answer:
The correct answer is OD. A flame is a type of fire, so when considering synonyms such as "flame" to help determine the meaning of "conflagration," it is clear that a conflagration must also be a type of fire. Therefore, the literal meaning of "conflagration" can be determined as a widespread and destructive fire.
Step-by-step explanation:
To understand how the synonym "flame" helps determine the denotative meaning of "conflagration," we need to consider the definition of the word "flame." A flame is a visible and gaseous part of a fire that emits light and heat. Therefore, when we use the word "flame" as a synonym for "conflagration," we can infer that a conflagration is also a type of fire.
The other answer options are incorrect. Option A suggests that a conflagration is a spark that may or may not ignite a fire, which is not an accurate interpretation of the word. Option B suggests that a conflagration is a relationship between two people, which has nothing to do with fire or flames. Option C suggests that a conflagration is some kind of lighting system, which is also not related to fire or flames.
Therefore, the correct answer is OD, as it accurately describes how the synonym "flame" can help determine the denotative meaning of "conflagration."
