The virus scanning technique that uses rules to determine if a program behaves like a virus is scanning.

a. download
b. file
c. heuristic
d. sandbox

Option c: Heuristic

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.

answer is:

a). backstage view

explanation:

backstage view is the area where files and data about them is managed— creating, saving, printing, sending to others, inspecting for hidden metadata or personal information, and setting options. so in this way we can add many things to our document swiftly.

i hope you get the idea.
