Answer:
Option c: Heuristic
Step-by-step explanation:
Heuristic scanning is a form of computer virus detection analysis that screen for the suspicious characteristic of the program which maybe a virus. Heuristic scanning is designed to detect those new computer virus, unknown virus or the modified version of the known virus.
To perform heuristic scanning, a weigh-based evaluation algorithm will be adopted to estimate the likelihood of the current scanned program behaves like a virus which can pose a computer threat. If it exceeds a threshold level, an alarm will be triggered.
