Model Answer
(C) False Positive (FP)
When the model predicts "Fire Present" (positive) but there is actually no fire (negative), it is a False Positive — wrongly predicting the negative class as positive.
Explanation
FP = model says "yes" but actual answer is "no." Remember: the first word (False) tells correctness, the second word (Positive) tells what the model predicted. Examiners expect the correct option plus a one-line justification.
