Answer:
B. There is a fire near the river.
Explanation:
Explicit details are details that are stated directly and clearly, without vagueness or ambiguity. Implicit details are the opposite - they are understood from the context without being directly stated.
Based on details from this passage, we can conclude that there is a fire near the river. There is smoke rising from the river and a fire truck driving towards the location of the fire.
The fact that Jonah smelled the smoke first doesn't mean that Angelo didn't smell it as soon as his attention was brought to it. The same goes for the fact Angelo saw the smoke first. It doesn't mean that he has better vision than Jonah; he was just the first to notice the smoke. The given details also don't tell us that the river is closer than they think.
This is why option B is the correct one.
