Answer:
The figurative language that's being used is: Metaphor
Explanation:
A metaphor is the figure of speech used in order to apply a(n) object or person. In this case, The vampire's eyes were being applied the effect of saying burning coal, bright and red.
The vampire's eyes = The object that is being applied to
Burning coals = The object that was applied to "Vampire's eyes"
A metaphor is basically when you are saying:
Something is something else.
Though similes are similar in a way, they can be different due to how they use it since:
Similes are when you say "Something is or are something else"
If the sentence were provided were a smile it would have been:
The vampire's eyes are like burning coals, bright and red.
