Target
An object or goal that one aims to reach or achieve, often used in the context of objectives, benchmarks, or physical marks aimed at in shooting or throwing.

Final Answer :
C
Explanation :
A false alarm occurs when the subject reports the presence of a target when there was no target present. Choice A is a correct response because the subject correctly reports the absence of a target. Choice B is an incorrect response because the subject misses the presence of a target. Choice D is not a response option in signal-detection procedures and describes a characteristic of sensory sensitivity.
